self portrait-optical illusions

I hadn't painted since my portfolio course so I thought I'd try get back into it. I'd been so used to painting with gouache and I really like the smooth finish of gouache paints and how easy they are to blend. You really only need the three primary colours. Unfortunately I had forgotten my gouache paints and only had acrylics with me. Also gouache doesn't work nicely on canvas, it's a very light paint and it seeps through the weave of the canvas.
 So it took a little while to get used to the acrylics and to mix the right colours. I was pretty happy with the result.

The optical illusion of this painting creates movement in your brain when there isn't actually any physical movement present.
