Jehan's new room

I'm really bad at remembering to take "before" pictures so these are "half-way" pictures. I need opinions! I was thinking of doing a few random blue and green stripes on the wall behind the toy shelf, but now I'm undecided again. I could do vertical or horizontal stripes, or blue and green polka-dots, or I could just leave it the way it is. Or something entirely different. Any ideas?





(I haven't painted the shelves or doors yet. They'll be white like the baseboards.
Here are the pictures I found online that I liked. I probably wouldn't do exactly the same thing for either one but something similar.
