Whereas my own Jess has very thick red tinted dark brown hair, I have heard that some of the Jess's have thinner hair. If it weren't for the fact that I ordered her the second she was released, that may have worried me, so I think it is worth being noted. You can always send a doll back until you find "your" Jess. That being said, I think that the slight yellowish tint to her skin is accurate, and her coloring is absolutely gorgeous. There is not a single outfit that I have which she does not look great in! She looks a lot like my Mother as a girl, and my Mother is of the exact same heritage (add a dash of German and English and Cheyenne Indian with the Irish from grandpa and a 100% Japanese grandma). I do not think they could have been more accurate except perhaps to make the eyes a "tad" more asian.
I had to line all of my dolls up to distinguish the different "tints" of skin. It's a very interesting subject to ponder!
