Here are some more mandalas that I have done. Before I started working digitally I used to paint. I had a shape that I liked to paint into patterns. On occasion, I would find myself creating a circular image. Here are a couple of my painted mandalas along with a digital one.
This one was created in Photoshop.
Size: 12.25" x 12.25"
I am considering altering the colors & textures.

This one is called "Untitled #15" or "Sundial".
It is acrylic on canvas board.
Size: 12" x 15.75"

This one is called "Altered Mandala".
It is acrylic on canvas board.
Size: 14" x 14"
