2nd batch of critique :)
Kadew: Dawwww I absolutely love it! You have a great idea going, and it manages to bare resemblance to Malaconda without being a carbon-copy. Your design is certainly a frontrunner, and it's easy to see why.. I love your adorably evil critter! (no I have nothing negative to say about it)
The Steam Punk: Ooh, interesting concept! I like the idea of having a leaf as its head, but I'm not really sure how it ties in with Malaconda :/ Your feet, whilst being mildly reptilian, look a bit odd in conjunction with your prevo's body, although I'm sure it can be worked on! I find the tail to be a little uninspired.. try thinking of something else to go on the tail to represent Malaconda a little more.
Knickles: As the others have said, the face is a little too flat. Furthermore, your prevo is a little uncreative in the sense that it bares so many similarities to Malaconda that it ends up looking too much like it. You need to find the right balance between looking too much like Malaconda and looking nothing like it. Of course, a lot of prevos do look like a smaller version of their evolution, but with all the competition going around in this thread, you need to seperate yourself out from the pack. However, I like the idea of berries on the tail, although it could be implemented a little better, and the one green stripe near the tail is a nice touch.
Hollymon: I like it! You have a nice element of cuteness whilst keeping true to Miniconda's dark typing. The leaf head doesn't relate to Malaconda, but you've given it enough resemblances that it ends up working. I love the idea of a giant apple seed, although it looks a little odd in your prevo's pose. I suggest reposing the whole thing and perhaps elongating its body? It seems a little short at the moment.
noobiess: Interesting...I'm a huge fan of the concept! Unlike others, I like how the head looks, although I know that's going against general consensus. The only thing I suggest improving is the positioning of the leaves adjacent to its head. I suggest moving them down its body a little bit, as in the current position it looks slightly weird more than anything else. Otherwise, good job! Also I like how your prevo gives leeway for this emoticon -> o3o
Blue Frog: Cute! Sadly, I'm not a fan of your design. The neck is so rigid that, when the face is added, looks more like a Llama or Camel than a snake. The colour scheme is an odd choice, mainly because your prevo has nothing in common with Malaconda. I feel like its dark typing is missing. This next point may be biased, as I am not a fan of feet on Malaconda's prevo, but I suggest removing the feet to get a better "flow" per se to your design.
Sgt.Moose: Very reminiscent of Mos-Quitoxe's :) I like the idea of it, especially that punk leaf blade as a haircut which represents the dark typing in an eccentric yet great wa, but I feel like this prevo is just stuck in an apple more than anything else. Show some neck coming out of the apple too, and not just the head. Furthermore, I am slightly puzzled as to why their is a stray dot on your prevo's tail...
paintseagull: Once again, it's cute, simple, brilliant work from you. You've managed to have a nice blend of cute and cheeky, and you've kept to Malaconda's design well. I won't comment on the tail because you said that you were changing it already, but you're certainly a frontrunner!
elcheeso: I like it a lot! The leaves on the head look odd however, as snakes don't have no outer ears. Other than that, good job!
