The second piece I was going to try to do both variations again but I stopped when I liked the way it was looking. I created the lines where I was going to make the mirrored paradox squares but thought that it would be way too busy. Keep it simple. I like it.
Oops, I just realized that I forgot to shade! Tomorrow I will add pics with the shading.Silly me. Okay, here are the new ones added on. As you can see, the second design got some waves in it as well. I like that better. Interesting.
