If I may leave a bit of constructive criticism, I think the face looks too female. If I didn't read the title I would assume it was another female character. I'm not an artist so I can't tell you if its the eyes/eyebrows shape/position if it's the overall face/head shape but it does look much more female than male to me at least. This is something that I also found in the other male character but with the beard it's easier to see it as male but since this one covers almost the entire face, for some reason the features that are visible feel more female.
You make awesome female characters but maybe consider focusing more on the male face features for the existing or future male characters.
Once again, your stuff is awesome so please don't take this the wrong way.
