thank you @simon62 both for tagging me in this challenge and for your awesome comment! I love that round about circle cycle of mental evolution you've outlined ;-) and yes those sunglasses were so much fun.. I drew a few pairs in different ways.. I got the inspiration from the artist Prince.. he had a pair that were circles but there was a third added on and I thought that was so cool - so I made a few of my own sketches. Glad you like them! ;-) Thanks for the resteem, too!
