great layout. I am not a fan of the image viewer stuff, but it is not a big deal. The vehicles look pretty sweet, although maybe the panel gaps are a bit big? The bed and ring look nice. The other stuff does not look as good, but still decent.
It it were me I would pick your best 2 or 3 characters, and move them down under the vehicles.
I think the Earthworm Jim and Kid Icarus are the best of the characters
