I love the concept. A geek looking from over the top of the cubicle. I like that it will work with print too. The colors feel a bit light to me (not bold colors). I think the guy is a little to complex. Can you make the guy a little more simple looking (not so busy with all the lines going everywhere)?
Can you change the colors on the text (use something a little more bold)? Change the text so that cubicle and geek are different colors maybe.
