I find hard and constructive difficult, especially with an image that was obviously edited to be artisitic.
Honestly, I don't like it. Lighting looks good, but contrast is too high, it's pixelated, it's noisy, the subject is very limited, and I'm not a fan of the framing...cutting off part of the hands just doesn't do it for me.
The photo just doesn't have any context. Like cloudwalker said, it would be much more interesting as a series with some pull back shots showing who the guy is. As it is, it's a pixelated shot of a guy lighting a cigarette. Without the story, it just doesn't do anything for me.
