Very nice set. I'll definitely buy a case of them. On the whole, the sculpts are getting better with each set, although the paint jobs have always sucked. Thats ok though, I just repaint what I want.
I really like the spectre, savage minotaur, salamander archer, zombie hulk, nightwalker (look, its not glittery!), legion devil, greenvine, goblin wolf rider, the githyanki, death giant, bullywugs!!!!, and the two dragons look amazing. The human outrider isn't bad, but I already have a ton of mounted metal minis, so this one isn't as useful to me, but I can see how a lot of people would like it.
The marilith is pretty bad though (as all of the DDM mariliths have been)- this one looks like Cyndi Lauper from the early 80s.
They would do a lot better if they didn't try to make the marilith look hawt, but more like a monster (maybe the medusa from Clash of the Titans with more arms?).
