I recently found this blog, and loved the idea, this week's sketch is really pretty, so I gave it a try, check it out at Retro Sketches.
Here is my take on the sketch, I just changed the panel to the other side.
Also this "kind" of qualifies for CAS-ual Fridays Challenge 48, I used TWO sets of opposite colors, aqua and orange, and red and green. So I think I'll sneak in there too. because I loved that challenge!!
