This is a busy shot, andto my eye the subjects aren't well enough separated from their background. A tighter crop removing the two guys in the rear might have helped make the three in the foreground more present.
seems that you lost some detail in the black clothes (or it could always just be my monitor)... I really want to like this photo, it has really the ingredients for an outstanding capture but i feel that as is presented it lacks a central point of focus, the balance of people on the page is not really strong compositionally, the problem with the darks, and i guess also the shallow dof./ lack of sharpness. 7
