This is part of an army that I am trying to sell, take a look: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MESELX:IT&item=180304779573
a nice well done table top mini. colors are all placed very well, and highlights are done pretty decently. i would however add a few strokes of skull white to the beard.
I would add a little bit more shadows on grey parts. Metallics could be more shadowed too. Skin is good. Try to paint base's sides for brighter color, for example bestial brown. It would look better.
I quite like this. It would be good to see different finishes on the metallics (some pieces 'antiqued' with maybe a blue green undercoat (like buffed ancient copper) and maybe a bit more extreme highlighting on the very edges to bring out the runes and other details.) Good stuff.
