Here we have my Orikan conversion all finished up. I made him a little swampy to fit the theme, but overall he is the cleanest of the bunch. I used the Cairn Wraith with a Deathmark head and a Rod of the Covenant. I used some Army Painter Battlefield Tuft on the base. Using a mix of that stuff and regular static grass you can get a really natural looking landscape with ease.
I'm pretty happy with him (though I'll probably lighten the grass on the arms) and next up I have a squad of Immortals. SWAMP.
