Yeah, this would be amazing in a lego stopmotion(nice use of ninja swords btw). add a red diamond in the middle of the thing in the tomb and make Johnny Thunder/Sam Grant enter the tomb, avoid some traps, get the diamond, and get out.
Impressive! And I agree with those who say you should expand the temple. It would look absolutley awesome if you would develop a temple complex behind that entire mountain wall. With that said, however, you may either have other plans or an insuffecient supply of bricks to do that. Regardless, excellent work!
