Nice concept! For some reason I think a lack of pocket-with-pens, or other typical nerdy-stereotype artifacts adds greatly to the humour of the piece. In my mind its like its this irritating jock guy who has somehow managed the award, and is lording it over his more nerdy colleagues. Obvious irony follows.
Shading is looking slightly pillowy, particularly around the entire crotch area (including hand). That lighter blue shade you're using to AA the blue outline against the grey is too bright, and gives a really nasty look to the outline, imo. Check out Panda's avatar, I reckon that could be a good inspiration style-wise for this piece.
In terms of background elements, I say decorate his office with things that reflect his character, whatever you decide that character to be. Maybe a photo of his family on the counter... maybe even just make them regular people, not insects, to add to the weirdness. On the computer screen you could have something that doesn't really relate to work at all, such as Solitaire, or something. Might be why he has such a snide attitude about his award.
The mustache isn't immediately clear to me as a mustache. Comes across as some kind of depth shading to his face, making it look like his mouth sticks way out. Try going for something more obviously separate from the skin, like a black colour.
Keep it rockin'!
