I enjoy the thought of the potential your art style could have, but it never hurts to say that practice makes perfect. The background, for instance, had a clear idea, but it doesn't feel as complete as I feel it could be. However, bits of it like the textures of the smoke and the face give me the impression that you know how texturing works in that sense. Keep in mind while you're working on pieces if you're completely satisfied with the work that you've made, so that you can question the things you wish to improve later on in the future. Keep up the work, honestly, I can't wait to see more from you!
