So here is a Pre-Heresy Terminator armed with Lightning Claws (of the Alpha Legion). The claws took a while to get right, my first attempt made them with the fingers too long so I removed a few joints from the lightning claws to shorten them. The rest of the model followed my standard method of construction, although I have to admit the shoulder pads were tricky.
At first I attempted them in plasticard but wasn’t happy with the result and so fell back on GS simply because I’m more confident with it. The claws were originally going to be used as masters to have cast, but I’m making another set for that purpose (more fitting for regular scale models). You’ll find a Mini-Tutorial on sculpting Alpha Legion icons here.
