Pretty damn great, i loved the character designs and the colors, very vibrant!
One thing i thought of was the punchline, it seemed to me that it was a little off...
Maybe a slightly more obvious correlation between the character in the ad and the boss' nose would've sufficed, something like a really juicy snort before he expressed his critique...just more emphasis on the viewer's assumption of what is about to happen, so that the contrast/punchline in the end ends up...bouncier!
All in all, pretty damn good and I await your future animations :)
