Arkeis - As I said earlier, I really like your design. I'm only wondering if it will still work as well when viewed from different angles. I hope you will be able to show more later!
Blue Frog - The spin you gave on the typing is really nice, and you made it work surprisingly well. If I have to nitpick, I'd say the pot could be even more integrated with the lobster somehow, especially the connections of its feet can be improved I think.
DougJustDoug - Even though its just a sketch, I think your idea has got a lot of potential (I had the idea of using the capricorn zodiac earlier). Especially if the CAP would turn out to be a fast special attacker (with levitate) I think your design would fit very nicely. Looking forward to the colored version!
Magistrum - I like both of your designs, with a slight preference for the homunculusmon I think. But I do agree with a comment earlier (don't remember whose) that the body should be a bit less prominent since the head is the best part.
miririri - Love it. Nice how you've managed to 'evolve' your earlier cutemon into a more 'fearsome' beast;) I'm not sure how you can improve on the current design, I like the simplicity. The only thing that I can see bring it down are stats/ability, but we'll see.
OldManDugan - I'm not sure what it is but your design appeals to me greatly:) I would love to see more of it. Maybe you could bring out the water typing a bit more, since right now I would view it more as a fire/poison type (I think someone even posted a similar idea in the Mollux art thread).
Precipice - The background story behind your vikemon is really cool and the way you're slowly enhancing the design seems to work out well. I think the more dragon-like head fits the design a lot better, whereas the serpent might make the water typing a bit more obvious. Even though it's a flaming boat, I think that because of all the draconic details, it might be better to use the serpent head. The dragon head might make the 'hidden' dragon typing a bit too dominant (yeah yeah gyarados...blabla;)
Yilx - I love your artwork (like always). I agree that the fire typing could come out a bit more obvious with some slight color/gradient adjustments, but overall it's not a big problem. Another - minor - issue I have is that it's somewhat similar to necturna because of the head/face and overall feel of the design.
I made a very quick selection of the designs and actually think I skipped over some that would rank among these as well. If I find some time later I will update with more comments!
