Received him this morning, and I think he looks great.
The un-helmeted head is just plain scary viewed from the front. There's something really off with the eyes. In profile from either side the sculpt looks fine, but as soon as you start to turn it the weirdness returns.
Always planned to have the helmeted sculpt on anyway.
The only problem is the height. Some of that comes from the length of the neck, and the height it's intended to sit at on the joint in the body.
So, once again, it's the Disney Krennic body to the rescue. It's about the same size as the Sideshow body, but it allows for the neck to sit lower on the peg. And I can remove half of the ankle pegs without having to break the legs on the Sideshow body.
The ankle cup halves that remain attached to the legs will just sit down into the boot recesses.
