Dark Angels Techmarine

Having taken a few days off painting to recover from my mental fatigue following the Call to Arms tournament, I've spent the last couple of evenings working on a techmarine for my Dark Angels force.

I've built him from an old space marine captain (I think), with the Halberd of Caliban as his power axe, and a servo-harness made from a couple of missile launcher backpacks, a flamer and a plasma pistol.
