Looks decent, but the style is pretty much whored.. and the theme is not creative anymore, but if this piece is just like a practice piece to get your creative spark back, then it has serve its purpose..
awesome, really, I love the whole concept. one thing I dislike is the empty bottem, but overall 8.5/10 definately . edit: is there a tutorial on this?
Although its a whored style, i like it. If you add your own unique touch into art, forget if the style is whored, especially if you haven't done any of this type of thing before. Now, i haven't really seen your other work, but i like the colouring of it. The rainbow and sky add enough colouring for the rest to be black, but i don't particularily like the things at the bottom. They aren't that... relative to the rest of the piece. Anyway, good job, and keep it up
