I like this! Love the lime green & shades of purple. It really has a spinning effect. I thought for a minute I could see it actually spin or was it just me. I think I'm a little dizzy now. Excellent work.
Simple but absorbing - thanks to the spiral shape and the loseness of the center. The colours are a little strong for my personal taste - but i can see the appeal (To me it looks like an alien barrel of a wave)- good work!
