Great smooth animation and distinct cartoony style. I think a lot of the reviewers here complaining that the girl from neck up was "unattractive" missed the point of the cartoon.
Her attractive assetts were obviously her boobs and curvy body. If she had been pretty-faced, the guy would've had less reason to ignore her and the cartoon's sequence of events and payoff wouldn't have been as funny and satisfying. The humor was just right with her being semi-desperate to get his attention by stripping down naked, but doing it in a classy way, and not completely self-degrading herself just for his sake.
Office workers probably wish this sort of thing happened on a regular basis, just to motivate them to do better work! Good job.
