Looks good, nice to see A good example of dual weilding also

Here's some feedback in case you ever do want to color it. It's just my observations/ opionion

my attention first comes to the skull and after some looking around I realized that it was an actual animal, probably something dragonish perhaps. I would assume it could be more easily recognized as being alive if it was colored or if more depth was allocated to the creature (like more outlining and a bigger size and might bring emphasis away from the warrior)

my eye is next drawn to the head covering, obviously for protection from the harsh desert sun. Yet there are times when it would be want to be removed and due to the design/ giant ears it would be hard to remove. However obviously this isn't very important if you don't plan on it being more than one picture

the sword seems almost too curved, I don't think swords are curved that far (though there might be swords for performance only that are that curved). Regardless the sword's hilt would be more straight for effectivness unless you want more elegance than effectivness.

Oh and not sure if you have it or not but if the hood was attacthed to a cape it would be effective logicaly and look good

this is just my opionion, I am not a proffesional artist so I see it differently than you might
and it does look good
