That mini is a part of my projekt: Battle of Osgiliath. In Background you can see some elements of riuned, former capital of Gondor (and my room;-]). Soon more pictures. Coments welcomed.
The strong point on this figure is the fell beast. there are some great colours in the skin and wings and the whole works well. I've painted one myself and know what a chore they can be. The Witch King hasn't worked so well. It looks like the paint is a bit thick on him and there isn't much depth to be seen on the metallics. His robes could do with some of the tones you have given to the fell beast.
