I really like the idea behind this wall and the colors and blended in details match nicely. But, your signature is missing in the bottom of the wall and it would be nice if you put some kind of description up there - how long did it take you to make it, where did you get the scan, etc.

I'd also suggest cleaning the scan of Sakura a bit more; it looks a bit too grainy like this. But if it makes it to the gallery, I'll fave it! Keep it up and good luck!
