I thought this would be an easy one. Was I wrong.
The shading and shadows seem very easy just looking at them. I've never looked at a watermelon so closely: the lovely pinky translucence, the nearly white edges where the light catches, the clear white rind and the tiny little ticks of green at the rind. The grass challenged also, and still looks a little like astro turf. Learning as I go.
Tomorrow we go to Altavista the site of 2000 year old petroglyphs.
So many things to study through painting. I wonder what it will be tomorrow.
