On the hair: I took a look at pictures of their painted studio copy, which was painted by Marike Reimer. As far as placement goes, she made the rose-side highlights broader than mine, but the stuff on the gun side was similar. So, I figure, if it's good enough for their studio figure, it's good enough for me. I made the rose-side highlight a bit broader and called it good. It's not quite as smooth as it was but it'll do.
I also started shading the dress. I need to mess with that some more to smooth it out. The transitions need some work, and the shade color is going on a bit blotchy.
