This sort of thing is why I think it can be fun to share our personal takes on these figures, but, in the end, it's all subjective, so for a lot of "fixes", I oppose fighting to get Hot Toys to do them.
Something like, he uses a knife in the movie and the figure doesn't come with it, ok, point that out.
Something like forehead could be lower or face longer, that's where our personal views come into play, and personal views are precisely why sculpts can seem off.
While some of the best sculptors can get amazing likenesses, they're all off in some way, no one can 100% perfectly sculpt another person's face, it's just impossible, each artist will have personal style and view influences in their work that prevent it from being exact. Only a 3D digital scan of the actual head could give you 100% exactness.
This thread is a testament, some see this portrait fine as is, others see major issues. Neither is wrong, we all see things differently. In the end, it's Hot Toys' representation, it won't be perfect for everyone, and ultimately, you either buy it cuz you're happy with it or you move on and buy things you are happy with, they simply can't satisfy everyone.
