THAT LAUGH! - color thumbnails

Here is more progress on the #painting 'THAT LAUGH!'. These are some color study thumbnails. Which one do you like best? Just like the tonal study, I decided to make a color study with traditional media too. (Unlike what I usually do, which is make a digital mockup and then just print it out for reference. Doing it that way saves more time, but after doing the tonal in pencil, doing the color solely digital felt like a cop-out to me.)
