One-Hour Sketches

Today I decided to share something a little different.  I do quite a lot of sketches and studies during the course of any given week, some related to whatever my current project is, some to learn something new or work out a technical issue, and some just for my own fun and satisfaction.  These are usually limited to about an hour, and often I'll use an actual timer; when it goes off, the painting is finished.  Here are five recent sketches, all done with oil on linen, and the dimensions are roughly 7x5 inches.
