My Tuesday landscape class met at the Timken Museum, our fallback location for rainy days. Our teacher took us around and discussed the rhythm of several paintings in the museum. Afterwards I sketched a bit and tried to include more rhythm in my sketches. I used gouache from a small travel palette I devised. The pink paint on the back wall is too thick, but by the time I got to the side walls I was managing it a bit better.
This is a pen and gouache sketch on multimedia paper.
