Wow! I just love that! It's perfect on your wall and I love your background color.
My walls are white and we're fixin' to repaint them bright white, as my husband is horrified by a wall any other color.
I would love, love, love to paint one or more of them robins egg or even a deeper aqua color. Sigh... Anyhow, I'm thinking it would look really cool to paint the wall just behind the rasterbation in a different color coordinating to your rasterbation, kwim? Like I'm thinking you could do it so the background is the same shape, but just a bit bigger so it will frame your picture, or you could do a more funky messy edge. I like it so much better with a color other than white behind. If you did this you could just do it at the same time as your wood pieces.
I think I may have to do this!
