I suppose I'll get my name in here if you want to draw a bat.
Rilvor is an anthropomorphic bat of the species Vampyrum Spectrum (Spectral Bat). Coloration of the main body is a dark gray, getting lighter near "undersides" (abdominal/chest area, sides of hands/feet) which becomes white on his chest stomach as well as down to more nether regions and the "inside" of his legs to a degree. White coloration also rises from chest in a peculiar fashion (You'd have to see a drawing, no words I know for it) up only the frontside of his neck and up to his face, which is white up to the eyebrow area except for a dark stripe down the "muzzle" area to his nose, as well as a darker coloration around the eyes (If you look closely, it is meant to subtly resemble a bat's skull of his species). Ears are large and have a "sharp" quality to them. Sports an impressive set of teeth (Spectral Bats are carnivores afterall...). Eyes are a dark icy blue color ( my own of course...). Wings are blackish-dark gray on the membrane. Hair is always very much long and crimson (I wish I could make my hair the same color, but being naturally black/very dark brunette I'd have to bleach it...so I settle for dyeing it black), either tied back or let loose on its own accord. Hands and feet are naturally clawed for use.

Rilvor has never been drawn with any clothing on (Which is fine since his lower half has never been drawn either...), but here's a sketch of the sort of things he'd wear:

(It should be noted in this sketch, his face or "muzzle" is not supposed to be that long, so refer to one of the others if you please)
The pose and such is purely your choice, if you do decide to try and give him a lower half and can't do clothing, try to conceal certain nether regions at the very least, reasonably well.
