Squeak squeakity.. squeak squeakerson. 

 Man do I ever love what you did with the wings animation!!!

Very nice, good job!

 it moves a bit too fast , but its cool anyways :P

I actually have an alternate version with ear movement but I didn't quite like it. I agree with the shadow thing, but the shadow is small enough I couldn't manage to make it shrink and grow very smoothly.

 Cool Bat!  This looks like a cool enemy for an RPG.

 I love the flap flap

wing animation looks just fine. an ear flap animation would be coold though. animating the shadow to shrink and grow might be ok too.
