I don't know if I like him or not. He's certainly better than Roboute 'stand and stare at the ceiling' Guilliman. But it feels more like he's running for a bus.
Perhaps it would have worked better if he had an axe arm stretched out ready to sweep into some enemies.
Something which could be modded, I guess.
The model itself is fantastically detailed (although I would have liked to have seen a beard). It's just the pose which leaves me feeling 'meh'.
