I think this is the beginning of a pretty strong abstract... I think your compositional choices on this photo are pretty good, but there may be a bit of room for suggestion here... I don't know how many different compositions you tried, but I'm thinking that a little rotation on the 'object' could create some more strength in the image. I think a slight rotation would create some diagonal strength in the lines of the image...
I like the starkness of the exposure here also. The high key creates a lot of good contrast and sets an interesting overall mood for the shot.
too bad about the shadows...I really like the image. better lighting would lessen the need to brighten this and delineate your subject better. good job.
