Really nice model, Only things I would say is that the cloak could do with some more ripples in it, It looks a bit flat at the moment. Also the head looks a little odd. The horn things look quite separate from the head and look very stuck on, not like they are part of it. Great JOB!
Overall, this is pretty cool. The chains in particular are very well sculpted. I'm not sure why but to me the head doesn't quite look right. That small thing aside, it's a great mini :-)
