This definetly catches the essence of the song. I like the composition and the colors. About the only drawbacks are the dark triangle at the lower right corner, and in the lower left there seems to be a bit of a shadow with the focus going a bit soft. (Particularly the lower left of the 50 cent/pence? coin and the note behind it at the lower left corner.) This is likely due to the angle of your camera. The bottom of the frame is closer to the camera than the top, which makes it harder to fit it all within the depth of field. Either less angle, a smaller (larger number) f stop, or fiddling with the manual focus, could help out.
Overall this is a very good picture and it gets an 8 from me.
The focus is a little off and the light is a bit bright. Did you use your flash. I have been taking picture with light from my window and am finding that it is too bright, maybe that is your problem. Try adding some more contrast to it. See how that works.
You know it's probably a shame but I'd wager to say that a lot of people won't see the wonderful composition in this image. You really can soak this up. Nice Job.
