Not that bad looking for a character. However, adding a background couldn't be too bad of an idea for this drawing. One other thing I notice that could make this even better is slight shading around the arm pits and a little shading on her neck so it looks a little better. As for her legs, have to say they don't look too bad and seem to be honestly what legs would look like if they were pointing straight forward.
I am guessing she is wearing heels which is why you only see a bit of the black tips on her heels. The torso piece is cute I suppose. Then the choker with a bell is also nice, can kind of imagine if she has it on though that it would be hard to sneak around and defeat her foes. The bunny ears just make the torso and heels obvious state she is dressed as a Playboy Bunny making it interesting. If she is dressed as such, all that is missing is some fishnet pantyhose.
The red eyes make one feel a little cautious around her but I imagine she might feel alone at times if everyone feels they can't approach her for one reason or another. The spikes on the wings are cool and I am guessing the needle gloves are her weapons too. Slight smile on her face kind of makes one feel wary as if not knowing what she may do.
Overall, not too bad, add some shading and a background maybe. Good work.
