Since I didn't care for the previous arrangement, I tried reversing the major elements...the unicord and the keyboard. I have put the unicord in shadow, which works very well as a lead-in on the left into the painting. It is a large object and by putting it in shadow, its impact is strong but subtle.
I still don't care for the bright light on the keyboard and the sheet music, so I will continue to rearrange the objects.
Another problem with this arrangement is that all the light and white objects are on the right and the darker wood-toned objects are on the left. They really should be better balanced with a better distribution of lights and darks.
I'll try again.
