its a nice idea for the wallpaper and great choise of colors. but still there are some parts that should be worked out. like the water behind her, looks like u used to much burned layers btw. to dark. another thing that is bothering me a lot is the typo and o_o why the hell are there palm leafs? XD i dont see any palms. if it is a decoration for the typo u should get rid of it cause ppl will think that u just forgot to extract that part from the girls scan
also the typo is not really great its to scratchy and its hard to really hard to read. and i think it would be better to place it in the left middle then at the left higher area.
btw did u ever consider to make wallpaper thats of a higher resolution 1280x or higher? cause it would make thinks easier to work with that resolutions for wallpapers :3
