Here are a few environment thumbnail sketches that i did one week when i had some free time. I dont often do black and white / value sketches, i prefer to work in colour, but these were a good exercise for how to make a painting read without using colour. I do quite a lot of quick sketches like this, but they mostly just sit on my hard drive so i thought id put these ones together as they make a decent enough set and were all done within a day or two of each other.
