Apart from agreeing with the crops and thoughts behind them i would have to say one basic thing: you are at 92mm and shooting at 1/25... which is very slow, unless you are using a tripod or support. The shot suffers slightly from lack of clarity either from motion blur (probably caused it on the guy on the left) or a bit of camera shake (probably accounting for the general "soft" focus the shot has on close inspection). Remedy for that is upping the ISO i suppose... what were you on?

i was taking pictures for a poetry reading last night and got bored with the style of photography and had my own flights of fancy so i could get through the 2 hours with my sanity intact Thus in the same esteem I was thinking in terms of a less "reportage" type shot and focused more on the game itself, thus taking the faces out of the equation. I did nothing here but a crop and sharpen:

You might even consider cropping out the wooden part of the rail to get rid of the chalk and focus more on the ball and cue.
Just a thought on how to approach a subject matter, because that really wast critiquing the shot itself.

Back on track here i think the shot is fairly flat, the rail is almost vertical in the shot and offers no dynamism in the perspective, moving slightly to the left or (i think might be better a angle) to the right would have lead the eye up the rail to the player and then the expanse of the table with the line created by the cue would lead it back onto the table... if you get what i mean... hopefully
