Aside from being way too small, I don'dt understand the message of the image. Beyhond that the composition suffers (for instance, the tree growing out of his head).
Image way too small and your primary subject doesn't fill enough of the frame. Too much distraction in the shot with overexposure problems to boot. Learn from this one and keep shhoting :) Good luck.
You are hurting your picture when you submit it so small that we cannot make out the details. The cross is hard to see, and the picture looks tilted to the left.
I really like the idea, maybe it'll be better if the subject is facing east, almost fills up the photo, in a black background with light passing thru a window. :)
Nice concept, but execution needs some work: The camera seems tilted, making all surfaces lean to the left. The photo is fairly flat with blown out portions in the yard, photo is too small -- push that 640 limit. Cross/tree/head -- all seem to grow together. I don't get the sense from the photo he is kneeling -- just standing behind a really tall table.
You shot is pretty small. If you need help sizing your pictures search the forums and also look in the tutorial. If you will tell me what SW you use I'll help if I can.
