I've been trying our drawing on a new iPad I got. I searched what program David Hockney uses and found out it's Brushes. I downloaded it since I figure if it's good enough for Hockney it's good enough for me. With my understanding of photoshop, I was able to comprehend the program in about 5 minutes. It's super easy and fun! I've got the tools set up so it's just like drawing in my sketchbook. Here's a couple drawings, Tooks playing at the Hive, and Chelsea Royal playing at a 'League of Nations' party
