Yes, it's definitely a good looker!

Now it makes a more sense to me.. those long holes in the belly pan were for gearboxes, not wheels. I was trying to figure out how you would mount the gearbox from the first post.

Were you planning this as a competition-capable robot (ready for bumpers), or more as a demo? If the latter, I probably would have made the upper layer a square rather than an octagon to better protect the wheels from bumper interaction. As a showpiece (or Recycle Rush), it's spot on. [Now that I notice there are no mount points for manipulators or bumpers, I'm guessing the latter.]

With the upper frame as well as the lower, it looks quite stiff for a 4-wheel holonomic drive. This may cause you some unusual behavior on uneven ground, with the weight being on two or three wheels. The cantilevered wheels may provide a bit of suspension to compensate for slight irregularities like a plate under the carpet, but probably not something larger. If you plan to drive on carpet on solid floor, again, not a concern.
