I just have a few comments here.
I'm not sure quite how, or why, but the Overfiend model looks slightly... "old". I'm not sure if it's reused or anything (wouldn't surprise me, heh) but it just looks... not quite right.
As for Lord Anthrycist, I'm seeing Marrowgar. I don't know why, but I can see some clear Marrowgar-i-ness, in that model. Also, I keep reading the name as "anti-christ".
