Well this one is definitely more like Futurama, unfortunately it's way too close. Use Futurama or Family Guy or Simpsons as a general feel for the soft/cartoony nature we're looking for, rather than a specific model to follow.
As for the font, these colors work a little better, but would love to see different types of fonts. Maybe something a little more Web 2.0-like. I do like the .com in the price tag though, that's a nice touch.
Thanks,
Andrew
