Looking at this sketch critically, her eyes are definitely still too big, and I was a little hazy on what to do with her neck, but overall, it worked out better than I thought it would. The only thing that I'm really dissatisfied with is that there should be a touch of a Chinese look to her face, since Caprice's mother is Chinese.
What made this a particular challenge is that the generic anime style (and therefore my own usual art style which is almost painfully derivative of same) is highly stylized. There are a lot of details of the face that just go straight out the window, or more accurately never existed in the first place: laugh lines, the upper nose, the folds of the ear, the philtrum, and so forth. Magic-ing them up from nothing takes some effort.
For that matter it was also necessary to figure out just how attractive I genuinely pictured Caprice being: again, anime style is no help as it turns all women into supermodels. I settled on "reasonably pretty" but not gorgeous. (FYI, I honestly picture Benjamin as more of a handsome guy than Caprice is a beautiful woman. Dr. Juruna, on the other hand, is totally hot.)
Anyway. Interesting exercise. Might have to try it again sometime.
