So I'm back to the hospital! Once again, I took advantage of people watching the TV in the cafeteria. I found that if I sat in the front where the TV was I could get a better vantage, while they were too distracted by the news to notice me drawing them.
Once again with the brush pen... I think I've been making some progress and really want to get better at it. I also want to keep pushing facial/body features, slowly but surely.
