Old Westbury College - 8 x10 Oil on Panel. I painted this one plein air yesterday at 5 pm and finished a few details this morning. I'm going to rate this painting as a B for a couple of reasons. First- I like the design, color, edges, and values. Second- It's the first time that I painted out of my comfort zone of 6 x 8's. This one is a whopping 8 x10.
