I especially like your Dragon´s heads (cool green paintjob) and the belt (great effect).Only the skull on the left Shoulderpad and on the Bolt Pistol look a bit unspectacular to me, perhaps you should first prime them in Scorched Brown and then drybrush in Bestial Brown, Bleached Bone and at last Skull white, that gives more contrast to bone paint. But it´s a very well painted model anyway.
