heyas; looking at it again.... i dunno, the light seems to be the right direction okay for me. but in the background, the shadows are fully saturated black, and on the figures.... well, they're not. maybe try even losing the lower/left edges of the figures in shadow. see how that strikes you. in fact, the highest contrast is on those.... bar things going across the back (whatever they are :) ), where the highest contrast should be at your point of interest.
