I think composition is excellent.
I think that the photo can be improved by taking out much of the extraneous stuff and making him more prominent.
I cropped down to fill the screen with important stuff
Then darkened every thing but him.
Took out type (that draws people's eyes)
Warmed everything.
Lens blurred the background slightly and darkened the periphery.
So the result is, I think, that he is the prominent part of this and the viewer understands that the subject is looking at the stuff that fills his vision. (and ours)
