i think you have a problem with style here, the head and the things around it are great but the "body" i don't think it works well when it's illustrated like that, i would of preferred if you'd of made it that the body peeks out as well, something more natural and organic and the flat background just doesn't have enough detail to convince the eye that there's "more" it's enough to add fog or small lights at the back i like that there are part that are flat but i just think it should be presented different
