Just finished unpacking Smaug. As I was the one who posted that I had avoided buying Weta after having seen some Kong statues that looked like they had been painted by a third grader, I can say that I am very happy with this. Is this a high end paint job that you would pay someone $500-$1000? No, but it is a very nice mass production paint job. It doesn't have all the finest detail that the proto did, but I wasn't expecting that. When I saw the picture of the one where there was clearly paint missing on the chin, I got worried. I'm pretrty sure that will be in the minority though.
Not that you should have to on a piece that costs as much as it does, but if you want some extra highlighting, do a little drybrushing. I'm sure some are protesting right now, but it's really pretty easy. It's an animal with some very rough skin. Probably get some amazing results, if so inclined. You don't even have to try all that hard to match colors. But.......as I said, you really shouldn't have to. Just some thoughts from someone who builds a lot of models.
