I've used the legs from the GW Finecast upgrade pack on the sergeant, together with a head from the Kromlech bionics set. The decals are nice and smooth - taken from the GW Iron Hands decal sheet, and applied with Vallejo Decal Fix.
As ever, this shot remind me I needed to correct the gun barrel (I misdrilled it, so I'll need to correct it with green stuff then redrill it!).
This guy has a FW head - I think Mark V.
One of my favourite heads from the GW Finecast upgrade pack…
