Painting Practice

I had to do some painting practice at work to prep myself for more painting that will be applied to the project were working on. I'm trying to do speedpaints of environments.. (which ive never done before) so doing this excersise i feel like im loosening up a bit. Im used to making things final and finished looking. Not so much loose sketches. So here's one environment. It's numbered in the order I did them. My time limit i gave myself is 30 min, but the goal of course is to be able to do these in 5 min. ;)
