Not too sure why but this looks like Khal Drogo mixed with Jax Teller to me! Think it is the colouring of skin and the blonde highlights that do it... but there is more, sort of that Humman expression.
I remember at first I didn't like this character. But he grew on me pretty fast because he seemed to genuinely care about Daenerys and do anything for her (and the actor that portrayed him did a great job). I miss him!
I think this may be one of my favourites of your GoT works, not only because he's my favourite character and it was uploaded on my birthday, but also the detail and texture are absolutely perfect! I love this so much, it's amazing!
