Thanks for the comments, guys. About the bump map on the sking of the character- I´ll probably try to do something quickly in Zbrush. Procedurals are good for the very tiniest bumps, in my opinion. Otherwise you get the “orange effect”. I didn´t understand your workflow with the vertex colors. What´s the process? I´ll definitely do a lot of post work on this in photoshp. The floor under him is part of this idea. In fact, the floor of the cave will probably be mostly covered in fog or invisible, as there should be a whimsical/ethereal quality to the transition between the room and the cave (which is a figment of his imagination, after all). I tried the darker color at the end of the tunnel, it gave it a rather muddy feel to the whole right side of the frame. The tunnel starts to look like the creature. About the light on the floor, interesting idea. I might try that after I´m done with this first lighting concept. I´ll definitely make an occlusion pass when I´m done, though actually I think that I might just paint the shadow details in photoshop, since I´m rendering in so many layers.
