Yeah, that's cool

I totally dig the expression and pose!
And yeah, he's got 'kinked black hair' [<- quote] and usually ties it back.
More info, in case you want it to be really correct to the letter, which btw isn't that important, who looks at this stuff when the face is well done

He wears 'layered shirts, armour and pelts' and his sword is strapped to his back. I'd make the skin a tad bit more brown, though.
Btw, there's a quote from RotCG describing Traveller/Dassem, which you nailed perfectly, imo

'The fellow was fit, certainly. But not overly broad or large, which so many mistakenly equate with prowess in combat. No, it was more an aura about him – even in repose. A great burden and a great danger. Not in the mere physical sense. Rather, a spirituality. Potential. Great potential to create. Or to destroy. And there the danger.'
Also looking forward to see the finished thing
