A recent realization of mine: having a lot of time to work on a painting is not always a positive quality. In fact, I think it can cause a lack of spontaneity, boldness, freshness and strength in my final work. I know this is very subjective, which is why I'm speaking for myself. Having a quicker pace and leaving things a bit messy always provides me with more satisfaction for my final product.
I think this is also why I have such a difficult time when I'm working from photo references. It's so tempting to get lulled into all the detail and to begin making smaller, picky marks. Here's a list of words that I want to associate with my work: bold, large, strong, free, loose, thicker paint, life, large brushes, not labored and broad.
