Environment sketches

Wanted to practice doing some environments as well as working on my speed, as I still feel a bit rusty in both of those areas. I find that sometimes I still get to caught up on details and end up wasting time, when I should be thinking about the entire piece first. So I spent about an hour or so on each of these. It was definitely a relaxing session, and I hope to do more of these in the future. Let me know what you think, and feel free to leave tips if you're have some. Thanks!
