This is of Steve as a detective.

These two are of a character from my book BONES. His name is Vex and he is a Nichromydis, which is basically a large bat-like creature with hooves for its back feet, two horns on its head, a long tail, spikes down its back, and two hook-like opposable claws on its wings. When it walks on all fours, it puts the claws on the wings down on the floor. It can stand on just its hooves as well and have its wings folded.
