I have made a few custom units for my army that I thought I'd share. First is Shadow Captain Shrike. He uses a regular assault torso with beaky helmet and a pair of Space Wolf lightning claws. The legs are I think Sang Guard, and he has a Death Comp jump pack on the way from the UK.
Next is Assault Chaplain who is also awaiting a fancy jump pack. He also uses a regular assault torso and Sang Guard legs. His head is from the Warhammer Fantasy Chaos Champion I believe. His Crozius was made by cutting the top off a 2 handed Space Wolf Frost Axe and gluing a banner icon on top, I'm quite happy with the result, although next time I would probably adjust the angle of the arm a bit since he is holding quite close to his chest. He also has a Space Wolf storm bolter.
Lastly is my Chapter Master. He uses a commander robe/backpack with iron halo and a high-collared torso. He also has the Space Wolf storm bolter and a grey knight sword.
Just thought I'd share these, let me know what you think!
