Lighting is hard isn't it? I would say that's the weakest point of the drawing, besides maybe your choice in colors, which is also super hard to get right. You need to experiment with saturation and shadows and basic lighting, the lighting in this scene shouldn't be as complicated as you made it. The moon shining through the spikes of the club might've made a more interesting piece compositionally.
Experiment with ONE light source before you go all bananas. The design of that club's handle is too unreasonable in its "this looks utterly useless in all practical respects for a handle" quality.
