I'm glad you are part of the forum Pixel, even from my limited time spent on the board I can see that you contribute a lot of good stuff here. I appreciate it. My only critique here is that you don't give much room for the fact that to some degree "likenesss" is subjective; especially when a sculpture isn't a perfect home run. You have made it clear that you think that the sculpture in NO WAY looks like Guinness. Cool, thanks. But you don't leave it at that, and every time anyone says that they even see a little bit of Guinness in him you for some reason feel compelled to object as if they are telling you "up is down".
I think most of us agree that the likeness is off, but there can be a spectrum of legitimate opinions of just how off it is. A number of people like you believe there is absolutely no resemblance what so ever, a few (though if so its a very small number) may even believe it looks exactly like Guinness. But it seems to me that most everyone else is someplace in between.
When I look at the details I see Guinness in places. Even though his eyes are a bit too squinty the detail around his eyes, the crease between the eyebrows and wrinkles around the eyes and the top of his high cheekbones, the profile of his nose, his ears. The problem with the sculpt isn't that the details are all together wrong it's that the proportions of each detail is slightly different compared to the proportions of other details which throws off the likeness as a whole. This is one reason why to some people some angles make the figure look more like Guinness to them than others. The problem is no one seems to be able to have a conversation which explores the spectrum of likeness without you shutting it down by declaring that that any talk of likeness is equivalent of saying "up is down". Not everyone is so binary in their view of "likeness" of this figure where it has to be absolutely one way or the other.
It's disappointing that Hot Toys did not capture the likeness of Kenobi better, it would be much more fun if everyone thought they hit it out of the park. But they didn't and now people want to take time and look at it closer trying to decide if it has enough likeness for them to make picking up this figure worth their while. Everyone has a different criteria, some may think a "generic" Obiwan is fine even if it looks nothing like him, others may think he looks close enough to Guinness under the right conditions, others will simply pass. But I think it's okay for people wrestling with if they are going to buy this or not to try and explore the degree and spectrum of ways this may or may not look like Guinness even if you believe that it doesn't look like Guinness to any degree. You and others have expressed a more than valid opinion that you think it looks nothing like him and very few would argue that they got it perfect. I'm not sure why room can't be left for people who are in the middle when it comes to likeness. Hot and cold may be obvious but warm is more subjective - to some warm feels more hot, to others it feels more cold. Almost everyone agrees the likeness isn't hot, but please make room for those who may think it might be at least a little warm.
