Image: Preferably this if you can somehow find the source for the lower left image. If not, this will do.
If you go for the second picture, feel free to add something to the bg/make it transparent - whichever you think will look better.
Color/s: Something that matches her hair.
I tried to create pattern of staples as background (similar to anime opening) but... meh, I don't know myself.
