Here we are at Cafe NERO with water brush and a small tin of half pans. Sketch and paint. Got too much paint on the page, having no tester sheet, and no rinse, just the water in the brush handle.
Actually, I did. Prussian Blue over the trees, and onto the grey windows. Definitely balances the blue in other parts of the composition and also makes the red redder in the building on the right. Also went over some outlines in 8B to strengthen them.
Afterwards, visited Olympic Studios and Sheen Lane for more sketching. . .
