That's cool, man
The best thing about this was the "Ren & Stimpy" like animation. It's just so cool to see people put so much emotion into the characters they are animating. Another example of good animating is when you showed all those people in the stands. When I first heard the title, I thought it was going to be a parody of a candy bar commercial. I have never played the guitar so I have no clue what "zoombar" means in this context. I wish I was that lucky to get kisses from hot girls.
Some of the stuff was fairly typical so I recommend maybe spicing it up a bit. It's kind of long for a commercial, but this is a web commercial after all. This cartoon and zoombar should please any guitarists. The text shown at the end was pretty cool especially with the different layouts you chose. I hope this website has gotten back by now.
