This is a time lapse of a painting called "First Run". The complete painting took me about an hour and 15 minutes, and this has been sped up 4x to about 20 minutes. There is no audio, but you'll be able to see my process for blocking in large color shapes, then using a blending brush to merge masses and sculpt forms. Here i'm using my Sculpt Brush (which you can purchase at this link) which makes for quick and controllable blends.
Check out a free YouTube overview of this timelapse that highlights Sculpt brush usage.
"First Run" is available as a high-resolution, layered file in ArtBag02
