Troll and goblins almost colored

I tried to use darker shades for showing which parts are further away, where features appear, and so forth. I think I had the wrong idea with Kartina’s thighs when it came to that, plus the face of the goblin standing on her shoulders was lost in the attempt. That’s okay though, this is a process.

I’m at a loss for the ground and the house. Should I just do the ground green, or mix it with shrubs and rocks? Should the house just be brown, or should I put more details on it?
