Tara, I happen to like the roundness. I am biased because I can never have any roundness or softness in my own bone straight hair, but I always admire the softness and or...gan..ic...ness...? of curls. The color has really grown on me. The curls look so much more defined. I think after seeing your picture, I like highlights more on curly hair than straight.
After reading Jean's input I wonder what would happen if you parted it further on the side. That would fluff it up a bit more on top. Right now it looks just barely off center. It has to be done when it's wet though. It doesn't look right or even stay in place when I try to fiddle with it dry.
