I basically have to do a 3d environment for one of my classes, and have to come up with 3 sketches of ideas, I'm wondering if you guys could critique the designs, and tell me which one you like better. I will flesh the piece out completely in 2d first, so these are really rough right now, just enough to get the concept.
Harvest moon in the mountains
The body of a serpent coming out of the clouds
A conceptual tree of life in the desert.
