I did this plein air painting the afternoon in the Texas Hill Country. I felt great painting outdoors, but the painting was very challenge to me. Since I have not painted much plein air. The scene was overwhelming, the colors were different. I was out my comfort zone completely. I can't use my still life approaches here. This is my first time painting cactus. I really don't know what I was doing. I let my intuition take the lead. My colors were undefined, and my composition was accidental. I just simply paint. So if you feel you don't know how to paint something, you just simply paint.
