Very nice and clean, looks smooth also. as others have suggested some blending work, or maybe use some inks/glazes to add subtlety to the contrast.
Just another thought maybe use some more metallics, i have noticed that the sword haft would probably look better if you ventured towards using them, and also on the gauntlets and blade maybe some shading on the metallics (if they are, its harder to tell if metals have benn used on the blade)
Still great first mini, hopefully one of many
