Oh, this is gorgeous! I was getting used to seeing more subtle colors, like soft pinks of roses and whanot. Then you bring us then, with these crazy colors, so vibrant and funky that they're practically moving!
I love how you have some really sharp lines in there, along with more subtle blurred ones.
It's also neat how the center of the flower is divided down the middle, each side with different colored petals.
My mom just walked in and saw your picture and went "Wow, that's cool!! Who did that?"
