Glad to see you're back in action, Feral!
I don't hang around here much anymore because of real life problems, but seeing your work always helps improve my mood
Traitor Guardsmen - great weathering/damage effects on the armour and the shading also looks real nice.
Possessed - I like the poses (and paintjob of course). I thought my LatD were complete, but those models are really tempting... Alpha Legion colours look really good on them.
Mutant - You're particularly good at these guys. Very Cthulhuesque.
Lord - looks suitably battle-scarred and menacing. Nice detail with the wing. The lords I've seen (not that many come to think of it - they're kinda scarce compared to Sorcerers and DPs) are usually waving weapons around and screaming warcries, but this guy's pose seems a much better fit for the Alpha Legion.
I see your skills have been noticed by the Chaos gods, who have granted you a Chaotic painting desk familiar.
