Having recently found my downloaded (legally from GW.com) Witch Hunters codex I decided a small force would be a nice accompaniment to my space marines. Now that probably sounds crazy as a basic sisters troops choice is £39!
Then I realised that, as a wood elf player, I have a fair amount of spare female parts. Trimmed down coupled with space marine guns, cut down power packs and green stuff they look quite good in my opinion. Here are the pictures (sorry for the slight blur).
And for the second part: A Techmarine!
