I'm no good at wings myself, but that's simply not how wings work. Shade at the top rather than the bottom, underneath the arches of the wings. You may also want to consider that the wings will be bent "forward" (as in forward from the bat's viewpoint) with the inside of the wings facing the ground more. Also since the things that encompass the wing are thin and rounded, try using thin highlights rather than trying to shade them.

Here's a two-second-made example of what I'm trying to say.

I really like that red muscular thing by the way.
