I've been bringing my pallette with three colors (ult. blue, some cheap yellow, and alizarin crimson) and white to some of the local cafes to paint in my sketchbook. I used the leftover red to make the second image, no plan, just makin' shapes. Then used my colored pencils to tighten things up and make some stuff. Yay for sketching. Definitely not acurate values and such, and I know theres a lot to improve on for color variation and depth, bla bla bla... I'm still getting used to this medium and for maybe 20 minutes, I can't complain.
Here is a colored pencil sketch I did from people I saw in Starbucks, minus the naked guy.
