As originally pictured, it lacks harmony. You have colors fighting with each other, patterns fighting with each other, and 'styles' fighting with each other. Sometimes having one of these elements fight with another will work, but not all three.
Change the border to red and blue, or red white and blue to bring the colors out in the Dresden. It shouldn't be too complicated of a border either ... Piano keys (wide strips) might work and "mimic" the Dresden somewhat.
I'm not completely taken with the birds in the corner .. wondering if plain red would be better.
