Thanks - Tim
I want to slap you every time I look at you avatar. How's that? you said to let you have it.
On to the picture, I think you've done a great job, the exposure and the lighting help set the narrative - "What is the boy thinking about/looking at?". Just be aware, if you print it, it might come out a little too dark so you might have to boost the highlights and midtones a little. I like the use of the contrasting background, it works with the mood of the picture.
Now for what I think is wrong with it. The first one is minor, it's where the background changes colour above his head. Like I said, it's minor and doesn't spoil the picture, I'm just pointing it out and most people probably wouldn't notice it.
The space behind his head is unnecessary and can be considered a distraction, that can be fixed by cropping.
The object in the bottom right corner next to his elbow is distracting, that can be fixed by cropping.
The final thing is the worst thing, the object at the bottom of the frame. It's bad for the picture on several levels, it shouldn't be there, it's a distraction, it introduces a curved line that spoils effect of the straight lines and it introduces a pattern into an image that is otherwise devoid of pattern and a texture that conflicts with the rest of the image. You might get away with including it if there was a little more of it, you covered it with some plain material and all of it was in focus (the slight blur attracts the eye). A tabletop would be better though, you keep the straight lines and you get some reflection to work with.
I've gone into this in detail because I think it's a great image and worth re-shooting.
