OK, just a quick mini-review about the major concerns then I'll shut up and take more shots:
As always -- its better in hand.
Tunic: not white! Its the right color! The rest of the wardrobe (boots, robe, etc) is all very good as expected.
The head: the hair is much lighter than the SS prod pics. Not blonde -- but it is a more mustard color. Don't freak on 'mustard'. The hair as you can see is darker than the SDCC prototype but has nice texture. The beard also has a lighter 'mustard' shade brushed over the darker underneath. Mine has some 'splatter' on the ear and side of neck.
The face paint actually has some warmth to it -- more like Luke than Han -- but its still a bit thick and hides some of the wrinkles. The eyes are great and so are the eybrows...phew!
The one thing I don't like is the gray highlights on the moustache and temples. Against his coloring, it looks blue and isn't blended to look real. This is the one thing that makes it look like a doll...and the one thing people will end up complaining about when they receive theirs. This will be Obi's "lipstick" error.
Beyond that one small error -- I do like this figure. Its much better than Anakin, so I hope that alone alleviates some concerns. There will be those that still want to drybrush his hair lighter. I can see that; a bit lighter might be better, but this is far from the disaster people were fearing.
Again, these are my initial gut reactions.
