Jamie Hewlett Guitar Hero II 360 Commercial?

I just saw the commercial for Guitar Hero II on the 360 … and I couldn’t help but notice the character designs look A LOT like Jamie Hewlett’s work.

If you don’t know who Jamie Hewlett is, he’s the artist behind Tank Girl and Gorillaz.

Anybody have any idea if Hewlett was actually involved in this, or was this strictly inspired by his designs?

Great commercial.
