Well have now added the arms, though a little more work is still needed, the epualettes are also finished. For his hand weapon I've settled on a Plasma Pistol in the end, I played around with the idea of a Plasma Weapon based on a Webley pistol as suggested by a few people on Warseer, but in the end time constraints and the realisation that to get detail in the weapon would need to be quite large put me off. The idea is something I'd still like to play around with though, maybe another model!
The only thing I'm not quite happy with is the hand, I'd hoped to cut corners by using one from the Cadian plastics, in retrospect I think it may be just a tad large as is, I'm going to try an shave down the knuckles a bit, if that does'nt work I'll go to Plan B and sculpt a hand instead.
Finally I've also started working on a base, working from a resin piece from the Citadel Basing kit and an Ork Boy, we'll see how it turns out!
...and yes I have just noticed how thick the hair strands are in this pic from that angle, I'll go back and sort that out!
