Because for me a figure is more than a head sculpt.
Bein' a costume junkie, IMO what distinguishes a "doll" from an "art figure" is attention to scale, materials, details, paint including shading and neatness, ability to hold a pose, strength of the underlying body. AND critically the price e.g., at the price point, am I happy? Form follows function.
IMO there's nothing remarkable about the costuming here, compared to a number of 1/6 costumes (or at least the ones I've purchased) and worse, InArt decided to make an exclusive out of something pretty basic to the character. There's some amateur mistakes like the huge coat binding (off scale) and hands that fall off and/or weak ankles and/or a figure that falls over. This isn't a 200$ fig; it's a 400$+ plus fig; but my new Boba Fett has perfect tiny seams and pleats, everything to scale.
InArt seems pretty pleased about the "thin elven cloak" but what I seem is inexpensive printed material - not woven - that has no finishing of any kind. The coat isn't leather which was surprising.
So I'd disagree that the costume/figure is exquisite. From what I've seen, I'll get a "pretty good but could use some upgrades if I want to work at it" figure. Because it's a 400$ plus figure. If it were a 200$ figure then I'd be - well, less cynical. On the shelf he'll be fine. But InArt could have done a bit more.
