Hey! Cool crossover idea. The main feedback is the perspective of the head. We're looking from below the character so the mouth and nose need to be moved up a little more. I'm linking 3 resources that can help you with drawing head shapes from ANY angle and hopefully it'll help you and your comic look more dynamic: 1.

In stead of a straight on view, it would look better if you turned the body a little to make it look more dimensional. I hope the sketch helps :)
