When I was drawing towards the end of me filling in my foreground and my background I took a tissue to rub in a give it a nice highlight. Then when we had the lights off, it broadcasted a shadow that showed us which way the shadows were coming from. I think my background and foreground show the best middle tone which eachother but so do the shadow. I gave the Glue bottle most of my time and effort but it also shows most of the indirect light displayed. The sphere displayed most of reflected light and around the vase I had some pretty good cast shadows.
