A first version of the cave with simple textures for the cave and the rocks. The sword of the skeleton was hard to see because of the rotation and the cave texture was not very interesting.
After a few iterations the cave and rocks got better textures and a second skeleton entered the cave. Also a few mushrooms grew in the cave.
Then I added fog so that the cave looks more mysterious and tested different light sources.
