Good dynamic positioning, enjoyable gradation of light across the face. Although the leg makes a leading line toward the subject, the strong contrast of leg against dark guitar holds my eye away from the main elements. In advanced editing, selective adjustment might help. In basic, long pants might be a workable alternative.
I like the composition of this. It doesn't follow the exat norms, things are cropped off, but it works for me. The dark, broading of a young kid playing the blues, picking through the music. I think it needed to be dark like it is, others might disagree, but I like it......
