I like that you took this photo from the side, and not the front. It would help if you could get the background more blurry, this will isolate your subject, and make that water bottle less distracting. I would also take the photo from a lower angle to give it a more interesting perspective.
Technically perfect, sharp, colors pop, maybe a little more blurred background (DOF).....7.....oops, just notice the guy blowing his nose, might had cropped that out......still nice...7
I don't see boredom in this photograph. The bright colors work against you here, suggesting that the mood is rather light. I can't see the smoking man's eyes, but his posture and the angle of his head suggest that he's concentrating intently on something, not bored. The DOF is decent, but I'd have preferred to see a blurrier background. The water bottle on the left is somewhat distracting.
