The Unpleasentness of Mogg - Environments exploration.

I have been set with a task to produce few paintings that could be used as a base for our Arenas. Unfortunately with these I had a very short ammount of time. Each of the paintings below were about an hour long so there is many things that I would definitely like to improve / change. While approached with the task I was given a sheet of paper with different names of the arenas that could suggest their look, setting and colour palette. Yet again I have been approached with another task that required of me to work in a short ammount of time with a very small information provided. 

I quite enjoyed working on these, though I wish I had more time to polish them up.
