I asked an artist I admire do a critique of my work. She said many things that I had been thinking of and gave me some new things to think about. I'm planning on taking a few weeks off to do some "homework". I want to practice ellipses (a lot), paint some white objects to get a better handle on value and also work on using more subtle color - less saturated color over the entire painting surface.
Also, I've been feeling pressure (only from myself) to create a painting every day. On days that I don't, I'm disappointed. Anyway, it's making me not enjoy painting as much because it's starting to feel a little like a chore to create a finished piece every day.
If I create something interesting, I may post it. Otherwise, I'll be back in a few weeks and hopefully I'll be better for it! If you have any good exercises you think I might benefit from let me know. This site has lots of useful information.
