I don't know what it is about anthro bats that I find intriguing. Maybe it's the challenge of the wings, especially drawing them as functional arms (though I cheated a bit with the pose... though I've got a page full of me just dicking around with arm construction for em). Maybe it's that head shape.

I can't remember which bat type I was looking at when drawing this. I was at  redneckfur's place and looking through his mammal book for things to draw, and the bats called. Evening dress seemed logical...
