Don't like any of it, to be honest.
I understand FW stuff tends to be people's 'centre piece' model, but I'm so tired of these ridiculous bases. However, I will concede that the debris bases look infinitely better that the 'cover it with dead/dying enemies' bases.
Bit of a thunder hammer fetish going on at FW?
The Techmarines are alright, but nothing special. Perhaps will look a lot better once painted.
The Ultramarine guy... well, shit. I hope whoever gave the green light on that sculpt is fired.
