.. but did I learn anything?

I did mess around with this piece on cardboard. I had a good time and there are certainly aspects of it I think are strong. However on the whole I'd say it was less than good. If I want to keep at it I have to figure out how to tie it all together. In theory there are as few as one element that can package this picture into a well balanced composition. But what is it/ are they????
