I dont lik ethe composition here. I think it is too mch on the bottom edge, the way it actualyl connects with teh bottom edge and no other one just looks really weird. I would say lose the lines at the bottom, the stars, find a better place for the thing in the top right and also the detailing is kindof too small, but I guess as a full wallpaper it would be much better. But yeah, I like it alot, just somethings I think you should touch up to make it much better.
