Another nice work. ^_^ I really like the starfield in the background, looks very realistic. The text I think is a bit too big, it kind of makes your eye jump right to it rather than the rest of the wall. Does that make sense? Perhaps making it a different color (like purple with a white stroke around it) and a making it a bit smaller might help. Although I do like the style and line effect you used. :) The effects you added around the girl are very well done, but I think it would be nice if we could see her face a bit better. ^_^
Overall you did a great job. Keep up the lovely works. :)
