Here is a painting of two mute swans that I recently completed using oil paints, alkyd, and cotton duck canvas. Reproductions of this work are available on my Red Bubble website in the form of prints, i-phone cases, mugs, acrylic blocks, etc. Here is a link to the website; https://www.redbubble.com/people/jsjschmidt2017/works/30920335-perfect-pair-of-mute-of-swans?asc=u. I am working on getting the original post on my Etsy site, but it seems to be having technical difficulties today. I will try again tomorrow, and if it works, I will post a link here for anyone who is interested in purchasing it.
