Start of First Painting

Following the success of the large scale drawing I've started my first real painting, and its big. This time I bought my own panel and gessoed it white before starting. ALso I did a small preparatory sketch before starting, which the painting has diverged from significantly. I think I pretty much have the under painting done and will move into color this weekend. I anticipate some challenges in this since I don't feel like I have ever mastered color, also I need to allow myself to the freedom to drastically change the composition as I add color, which could become a mess.
