in the game super mario galaxy 2, you see bowser extra large (finaly, nintendo gets it, bowser should be big!). When you first fight him ingame. on the level bowser's lava power party! you see him sitting on a building of a throne. I built off that design from the game, tweaked bowser's over all build and edited the throne.

Also i made him WAY bigger, as that is a planet in his left hand, and a big planet at that
