Throwing my hat in the ring! The idea is a hand painted rendition of the Temple Fortress/Shanty town area from the most recent Tomb Raider game, using a vibrant WoW style pallet.
As we can take creative license with this competition I am going to fiddle with the layout a bit to make it fit the Diorama aspect of the challenge, the current plan is to do a tall diorama with a mountain either side and the bridge crossing the chasm. If I have the time I'll try to build some modular shanty stuff around the bottom of the mountains, giving the piece two focal points, however I will primarily focus on the Temple side of things, possibly having it fade out into a bed of cloud or something if the time doesn't allow me to do the shanty town.
This should be fun!
Heres some screenshots of it in game -
