the bluey dragon at the bottom of the page.... http://demonwinner.free.fr/germany/2008/golden_demon_winner.php?categorie=3
It is a conversion of a Abyssal Terror and a Carnosaur.. well.. Two Carnosaur heads.. The abyssal Terror is from the Vampire counts. Atleast.. it looks like it.
Hmm I actually think the whole body is carnosaur as well as the heads, judging from the third and fourth pics. The legs and claws look the same. Just a custom tail and I'm not sure the origin of the wings... Either the GW plastic standard dragon wings, or maybe custom made.
I think I saw a WIP of this guy, the second head is all GS. I remember thinking awesome sculpt. The wings are deff hand made.
