i agree with the blood fact (like it would never stick to his knee like that) but yeah the face is well done. the armour does lack some luster. a light drybrushing on the edges with a slightly brighter gold could do the trick while keeping the battered dull gold look it looks like you were trying to aim for.
the face is pretty good, but the gold TMM, is not interesting at all, seams like you didnt work enough on that, no highlights at all on the gold.
Rugh blending on some parts, like the skulls and cloth, blood effect seams messy, like slime instead of pure blood from a human...i am sorry for my critic but its only because i want to help you get better =)
7++ from me, happy painting
