I've attached a slideshow of my most recent painting. It's 6"x36" oil on canvas. I had a little trouble deciding on the background color and I think the dark works. It's a mixture of prussian blue, ultramarine, a touch of alizarin and an even smaller touch of cerulean blue. I tried a lighter background and it took away from the bottle. This was one of those paintings where it was mostly finished in a couple of days. It took an additional 4-5 days of staring at it and messing with until I was happy. This painting is sold.
