Well, he looks great for his age :o) Nice composition, I like the position of the 'model' in the frame. If it was my shot I'd have cropped the tiny git of detail on his t-shirt at the bottom of the frame out and possibly tried to get rid of the yellow sticker underneath his hand (some how) as they are a little distrcting...but then again I am very picky! ;o)
Really strong image: the bars and the tones of grey and russet work so well together. The expression says it all - in fact it could speak for itself without the title. I think the whole composition comes together really well. Good Luck!
