The animation is a bit awkward, and the shoulders will be redone..Other than that, any C/C?

PS: sorry about the lack of transparencies. I hate Microsoft Gif Animator
I like this little guy. The only thing that bothers me is how the wings flip upside down.

It's a good idea to rough out some animations in a solid color to see how it'll come out before putting the finishing touches on it. I'd suggest looking at how birds flap their wings for reference (Which I didn't actually do for the edit, but y'know...). I made a half circle with it's center at the joint where the body and wing connects to keep track of the wing span and make sure I didn't exceed it on any frames. Then just blotted out the shape of the wings in a solid color. Once you're happy with the way it looks, then it's time to put the finishing touches on the rough parts.

Other than that, good job.

Alright, I'll work on that. Thanks for the advice
