I had a lot of fun with painting this scene. The idea behind my scene is sort of an inhabited planet with a farming compound of some kind. There's a sort of toxic feeling with green and purple elements, maybe it's not inhabited by humans :)

The first take

 

More developed

After looking at this a little longer, I  saw some edges that felt too flat, and I wasn't really happy with the foreground rocks, so I tried to develop it some more.

 

Final
Here is my final, which I am pretty happy with, but I'm open for feedback on how to improve it more.

 

Great class! I really enjoyed the process.
