There's a 360 spin on the FW site, even worse from the rear. It's a common digi-sculpt rookie mistake, lazily rotating the arm from the wrong place - in this case somewhere on the ribcage. There doesn't appear to be any movement of the shoulder either, something GW figures don't often have as they're mostly modelled in rigid armour and shoulder movement is never factored in, but should have been done in this case.
