i like it, it's cool, but since you said 'more or less' complete, i take it you wouldn't mind more armchair criticism.
decadence has a point about the emptiness of the background, if your goal is to present a full reality. right now i think it has a kind of stage play quality (as if the fence is a prop, and a lighting director is working a couple of gels) which is effective in its own way.
i still think a layer of highlights, pale and stark like the light on the fence, would be good on the figure. the fence shadows suggest a light source a little higher than the fence top, not too far away. bouncing that off the guy would give you 3 elements acting upon each other in a little ecosystem, so to speak.
anyway, i'm not here to teach you the right way.. just trying to lend another perspective to the group observation. that's what i hope to receive when i share something in progress.
ps. in my previous post, i typed '_______' meaning 'you fill in the blank.' that was just an imaginary jumpstart to help you choose a name for the illustration without having to name the character.
