I haven't really worked on my 25g submission yet, so I will get to that later, but in the meantime I decided to make some comments on the existing designs. Don't take my comments too personally, they're just some quick thoughts. Sorry if I miss anybody.
ZardX I'm not really sure how all of the bushiness on the body is going to come together without looking too busy or just generally strange. The floatie things on the neck also look weird.
ShunosaurusLii So I love dinosaur Pokemon, but I think yours looks a little like a prevo. It needs to be beefed up a little bit to look like a final evolution. Get some spikes on the tail or something. The other concern I would have is most dinosaur pokemon are fossil Pokemon, not starters or the like, but I suppose we could choose to break that rule if we wanted to.
Magistrum I like your second version better than your first, the first was very Chrismas-y. It still lacks the Electric element a little bit in my mind, because I think the railgun antlers can still look a little like branches. May a little bit of shock decorations on the legs or around the antlers. I really like your art in general, so I'm being a little picky because I know it will be a very plausible option for 25g if you get a good designed nailed down.
Quanyails Personally, I like where the giraffe is going. The dandylion is cute, but almost too cute for a final starter evolution. Plus, giraffes deserve more love than just Girafarig in the Pokemon world. I'm not quite sure about the antennae, because they look sort of bug-ish to me, but I really want to see another iteration of it. The only other thing that I'm not sure about is the leaves on the legs, but I think they could work if they were sized and colored correctly.
Nektùll This is my favorite entry so far. It's just the right amount of ridiculous, but also well drawn and fits the concept super well. I don't mind that the body supposedly looks Grovyle-ish (I honestly don't really see it) I like that shade of green, and starters often have similar coloring - take a look the line-up of Fire starters through the years and compare the shade of orange used in like the first five of them.
Go on. I'll wait. Yes. They used almost exactly the same shade of orange somewhere in almost all of them, often for a large chunk of the body. I don't even have a suggestion. I like it the way it is.
StephXPM I really like the mad scientist concept and the art you have for it so far. It might be a little hard to tell that it's a Grass type, but color can always play a big part in that. I like the flytrap idea because it adds to the plant elements.
Zephias This is kind of an odd design for a starter Pokemon, because they always have faces as far as I can remember. It makes them more identifiable. (They're also usually animals, but I'm not too attached to that.) Maybe blend Audrey and an animal instead of a machine would help it look more like a Pokemon.
DrifblooomCF Like I said above, I like dinosaur Pokemon but it is a little unusual for them to not be fossil Pokemon. Assuming we're willing to ignore that, I have some other comments. The hair is kind of odd. I get it once I read your background text, but at first the afro with random black dots seemed out of place on the design, like it had a second set of eyes. I like how chill it looks though.
Wulfanator72 It's too bad you don't have much time, because I would like to see your design fully fleshed out. I think you have a good start. See the above comment I left for Drifblooom regarding dinosaur Pokemon as starters. A little decoration on the back to make the body less empty might also be nice.
DatHeatmor Vast improvement on the first design, now it really looks like a fully evolved Pokemon. I like the tail more than I expected to based on the first design. The pose and the colors are good also. Its head looks a little short to me, but maybe that's just because it's at an awkward angle?
Gravity Monkey I like the concept and the headdress. I'm looking forward to see what changes you will make to the bottom of it. Maybe it would be interesting to see what it would look like with a little more height on it?
Jackii I don't think your design if overdone at all. Other than the snail, which just amuses me hugely, yours is one of my favorites submitted so far. I think a little bit of yellow in the color will be important to show the typing, but I like the level of decoration and the frill behind its head. The arms look like they're at a bit of an awkward angle, though.
Zephias Aaand, we have another dinosaur. That's unusual for a starter Pokemon, dinosaur Pokemon are usually fossil Pokemon. If we assume that minor deviation from the usual is okay, you have a pretty cool design that needs a little sprucing up. Maybe it would look a little more like a final starter evolution if you added some grass decorations behind the head, or along the limbs. Just something to try out.
Brodaha This is super funny. It doesn't really look like a starter Pokemon, and I'm not sure how to make that happen, so I don't have much to comment on from an art/design perspective, but thank you for sharing this amusing take on the typing with us. More grass elements would definitely be a good thing to make it look more starter-y.
Nuukia I like the concept and the coloring, but something about the proportions of the head to the paws looks a little awkward to me. The head also seems to be reared back. I think a little bit of work on the proportions and pose could leave you with a pretty excellent entry.
Liam Nee-san Your entry looks pretty cool, other than it looks like it should maybe be Electric/Flying instead of Grass/Electric. I'm not sure off the top of my head how to incorporate more Grass elements into your existing design, but that would be something to think about.
Lukas0803 Your entry is very cute, but it doesn't really look like a fully evolved starter at this point. A little more complexity in the design of the body or face might help. Think more leaves or something. Also, think about how the legs are actually connected to the body, because right now I have no idea how that connection would look if it were made into a sprite.
SunriseInBlue I like your design pretty well, and I'm onboard with the alien theme. I looked at your alternate design, and I actually like that better. Maybe because I feel like it resolves into a coherent entity better, or something. I'm not really sure where you're going with the lemon eyes though. I'm also trying to figure out what texture the skin would be, since there's fluff all over the rest of the body. Is it shorter fur? Is is smooth, like alien skin? The world may never know.
There. Done, for now. Possibly for a long time. So much commenting. Why do I do this to myself.
