I have very actually never drawn an animal before at all, but i tried! many of you will probably be able to pick out glaring details xD; though i would love critique! I had a really really hard time trying to cement a design for him. I'm kinda torn between how to distinguish his bat features, but i went with a more cartoony design as far as his anatomy and whatnot. ( not mistakes, but instead of his legs having webbing and etc. )

i would love advice to help me figure out animal anatomy more, so if you have the time, please red-line/pass on your knowledge!
