Pretty cool. So this is one of your charaters?

I do have one character based off this design. His name is Haemaeo. I haven't gotten a good enough drawing of him done yet.

Not Good enough?
I might argue that :P

The world could use more bat-creatures.

...and arm-wings. Those things can be a nuisance to draw, but you've pulled them off quite nicely. Hardcore! (Are they actually translucent, or have you made the right elbow (in the leftmost drawing) visibly through the wind membrane for the sake of getting the design down? I've been toying with the idea of translucent wings - it makes things much simpler. ^^)

I like the thick, fluffy hair around the legs. This is quite an interesting design!

I had originally planned to make them fairly standard opaque wings, but I think once I start doing colors, i might leave them more translucent. I saw a bat done like that recently and I really liked the look. I think I am going to keep the transparence fairly light though.

Those wings are hard to do, especially the far side on the back shot. Oiy.
