Hey Souly. Nice stuff you got going on here. So good that it inspired me to do an edit, even though it's not so cool:

I gave your walkcycle a go and tried to improve it. Sub-pixel animation works great in theory but it's pretty hard to be done.
One thing I've also changed is the dark horizontal lines on the "ears" (looking like an "E", close to the head) and the dark stripes on the body. I think it really hurt the character's readability...
I also took your saturation courageous enterprise and made things more colorful. I've used the previous green "skin" tone, because I though it look better close to the orange.
Concerning the animation, all I did was stretch his arms a little bit further on the off-ground frames and tweaked the pixels of the "antennae" thing, in a desperate attempt to make the perspective look more natural on the frames where the head is turned.
I don't think my edit is a complete wreck but it's not so good either.
Anyway, keep up the good work! Looking at your mockup definitely makes me want to try the game. Will it actually get to be a game? I hope so!
