While I love oils, I work naturally in acrylics. The reason I take to acrylics is that it forces me to avoid some bad habits: over blending and noodling. These were done at a figure painting workshop, each of these is 20 minutes! I used techniques I learned from Craig Nelson's quick studies class. Craig is a great teacher, he has a way of teaching artists to overcome their fears and just going for it. His book and video on quick studies are good lessons for anyone interested in painting in oils or acrylics.
This was another acrylic quick study done on location in Sausalito.
