You should always take advantage of the size image to make your work sing. Bumping you up on composition as I think your focus begins one third up the image.
this is probably a very nice composition. but the size is too small, and more importantly the focus is missing. (unless it's very far back, in which case it's bad focus, not no focus).
keep at it!
I like the idea. A music note. The clarity is a little scetchy though. Looks blurry/ out of focus. I made a guitar out of CDs. its on my portfolio if you want to look at it.
Way too blurry and dark, it looks almost as if you took this with a cellular phone with a camera inbuilt. Perhaps you could improve on this by using a tripod if this is the result of camera shake.
This image had a lot of potential, but suffered from file size and dimension. You're allowed 640 pixels on one edge and 150k bytes... You should really try to use them all as it makes a huge difference in what the voters see :)
I'm afraid this is going to be attacked from all sides! A few suggestions:
1) subject matter of CDs has been done a lot and this doesn't make me stop and think 'hey, great take on the subject'
2) focus is badly off
3) use image editing software to bring image to as near maximum allowed size as possible
4) lighting and background are not very good
Keep trying, good results with low-spec cameras are definitely possible so don't lose heart
