Sketching California Hills from the Top of the Hill

I went to sketch the hills from the top of another hill - with my “Deck of Textures” co-teachers and friends Uma and Suhita. I did two takes on each view. A grayscale version made with three different grays: liquid charcoal, ink stick, brush pen filled with diluted ink. Second - gouache. My attempt to not pay attention to the only two trees with the bright autumnal foliage resulted in completely ignoring them (these hills are mostly covered in California oaks). Second pair is stencils and a smidge of gouache and gouache in my toned paper sketchbook.
