Nice image.. .i bettcha this was taken at Brunswick High School. Good job! I like how the broken glass is broken! This image is a little bit out of focus, but nice job.
Good subject, but it's a little overexposed in the highlights and a little too low res (I'd look at your resize/compression settings). It's also a little flat - try getting down amongst your subject to make it a bit more 3D.
a bit jumbled...even thought that's probably the point. I think a different surface would delineate a little better. I might have cheated the hue a bit too, to make the glass more uniform, but that's just me.
