So I received the regular version of this guy earlier today and just had a chance to take him out for a bit. Straight out of the box and posed, no modifications, minimal futzing to the robe:
"In time, you will find that it is you who are mistaken. About a great, many, things."
I gotta say, I'm pretty impressed with him myself. The sculpt is very detailed with all the lines and wrinkles in his face. Eyes can indeed be more yellow though, and while the expression captures him quite well, it only does so from specific scenes and he has to be posed based on those specific screen shots when he had that expression, otherwise it just comes across as looking goofy to me if he's posed any other way. People have mentioned snipping the threads on the sides of the hood that hold it down to the robe, and while you'd probably get optimal results with the hood if you do so, I actually don't think it's really a necessity the way it was with TFA Kylo Ren. The edge of the hood has a wire and can be shaped to drape close to his head, and the bottom edge of the robe has a wire as well. I didn't put the cane in his hand so I'm not sure how that fits in his hand. Same with the lightning attachments.
All in all a good figure. The hands and the robe look a bit more poofy in the images than what they actually are when you look at it in person.
