This painting didn't turn out the way I imagined, but I did learned a lot from doing this painting. The painting did fit the very early concept, but as the painting progressed, the concept kept on changing.

After the initial sketch, the painting needs time to mature in your head. As you look at the sketch over time, you might add new things. At some point there is nothing more you can do but to start painting. It's rare that a new concept is fully formed and it's ready for paint.
