Those images look very good! Take a look at this preview showing a possible new background. I slightly darkened the beach background so that the photos would easily be what your eyes focus on.
The screenshot is from my monitor, which is rather large, but I wanted to keep the photos small enough to be seen on laptop screens (1366px wide and 1440px wide). As you can see, the photos take up almost all of the visible space on the sides (unless the viewer has a large screen like me), so I didn't add any musical notes. If you really want them, let me know. I could put them outside the photos (the far left and right sides), but then only people with a large screen would see it.
