Aww, such a beautiful gift for her, i very much just love the theme. ^_^
Sugestions? I'm so very lousy at those but i'll try. ^^;;
If it was me i'd have the soft light from the stars/moon a lil bit more spread out, and add shadows/highlights/glow effects to her. ^^
-giggles- ...But then i'm always going perhaps too overboard with coloring, it's such a lovely pic as it currently is. Awesome work. ^_^

good idea! See, I loves your artwork and I'm still fiddling around with mine so comments always help.
