Interesting. He reminds me of Geralt from the first Witcher game...? (only bit older?) (Unfortunately I have not yet read W. series books, so I cannot compare your pic to books descriptions.) Quite do difference from TW3 game; there he was quite the looker (and charmer).
(I had him modded (to look less like normal human) and still he was... just... mmmmm, I understand those sorcereses, I would bang him too. Hahaha omgforgeti'vesaidthatplease.)
But this yours Geralt? He really looks like someone from Middle-ages, someone who goes through some real hardships, someone who has hard life, hazzardous profession (well, duh, he is Witcher) etc. etc.
He has interesting look in his face... it's... as if he has tired eyes. And yet there is... idk... resolve? in him? Certain determination, a core of steel, will(power) to go on. He may be weary but he has Path before him and he's going to walk it.
Aaah, ignore my ramblings, my brain is half asleep (it's midnight right now). It's just... bloody good portrait.
