I started doing these 30 minute warm up sketches about two years ago. They're primarily scifi and fantasy inspired. The exercise has become a favorite part of my daily routine and has greatly improved my full paintings. They're all done from scratch in Photoshop, with a large collection of custom brushes accumulated over the years.
These are some of my favorites from this year, but more can be found on my website, http://www.kcgarza.com.
