Thanks for all your comments so far!
I've started adding some test colors. I also changed the head, fixed his tail (I wanted it to be kindah long, but it got a little too long i guess ^^). With colors, what I was going for with his tail might be a little clearer. It has a fin... thing.
I'll see what I can do with the wings, I'll scrap the current ones and add smaller more cartoony wings instead. Added blood on his fangs, no particular reason. I just messed around a little.
He won't be able to fly, but in true video-game manner they help him to jump higher
EDIT// I was meaning to do show this as well.
Although the two versions are similar in size I felt that this was a little to big a difference.
