Yes, I have been bottle shopping. I found the brown bottle in an antique shop on the discount shelf! And the other, which contains oil to lubricate fishing reels, at a local consignment shop. What treasures!
I started with a sketch using burnt sienna. This helped me to see the shapes and shadows before committing to the color. I was happy with the negative space along the top, and the light shining on the back pear through the brown bottle, and the light shining through the front bottle. There was a pleasing movement to the whole painting.
