Daemon & Grey Knight Board:
Simple snow basing with a few casualties to spice it up.
Eldar Corsair Board:
This board is the more unique of the 2. I have been basing my Eldar & Dark Eldar with a bit of wraithbone showing through debris & grass, now you can see the overall look I was going for: a ruined Eldar city, possible on an abandoned Craftworld or Exodite world.
I have Dark Eldar on the left & Eldar on the right, although all are Corsairs.
