But yeah, the paint on both Luke and Han's faces doesn't have much HT-style gradation and it is definitely a shade too dark brown complexion-wise on both (a bit like the Tauntaun facepaint actually.) Both hatless sculpts are awesome, hatless Han (which I don't think Rorywan has) to me is noticeably batter than hatted Han. Both hatted heads - Luke and Han - do have a more dead look. Same face sculpts as the unhatted obviously but I think the hat construction distorts the face/eyes somehow. Still look really nice overall, just a little off.
Definitely agree that the complexion is a bit too dark on both Han and Luke. I think they got it more right on the exclusive Luke, which also probably photographs a bit better than the tan sculpts since cameras color correct and wash out those sculpts a bit--plus the battle damage helps, which is promising for Indy (I was jealous of the exclusive Luke on eBay we saw and then I photographed mine and realized it's just as good).
Don't agree about hatted vs hair sculpts though. I'm totally more on board with the hatted sculpts, though I've warmed up to Luke, so maybe I'll do the same with Han at some point. Again this bodes well for Indy, though maybe not for everyone.
