I think it looks nice, but the generic shop is still a mess. Might want to make profession-nanos into the profession-vendor and just make the vendors usable by all. Also, the vendors (including the rocketguy and barkeeper) should probably not be in the duel-room cause it can cause errors when tabbing and using the mouse during duels. Adding towershop-vendors to the hub might also be an idea.

Some might want a pillar in the duelroom so they can use los, like u see here:
