This is really a beautiful peace! :) okay here's my note, i think its much better without the typography, or you could just make it more simpler just a little size. agree with sir meng on the lights. but overall this is really good! just a few tweaks :)!
NIce work. Since you requested a feedback:
First of all, I think those white lights could use more work/definition. It's too linear and distracting. The background looks nice, but the lighting doesn't flow with her wins and the person. She looks flat. Finally, the text is too big. You ned to work on your typography, or if you're not comfortable, make it much smaller. It's a wallpaper after all. :)
