Studies the top one is a Richard Schmid, I really love that paining. I tried to replicate the brushstrokes as best as I could. He (like many Masters) has a effortless look to his brush strokes, almost as if his brushed danced around the canvas. I admire that look and strive to have all my paintings look that effortless. However effortless is far from how a painting like that is accomplished.
The second is a photo study just like the way it looked and the reflective light on the rock.
