He looks incredible, man, especially the confidence I feel from his body language and expression. I am writing a story and I felt chills looking at your ranger, as he has the likeness of the father-figure of one of my heroines. Would it be okay if I used this character's likeness for him? Of course, credit would be given.
Sweet! Love the detail; even his skin looks rugged. Very practical armour, too.
The only criticism I have is the fingers: he's got no grip: it looks like he's holding the khukris with his fingers almost flat, sort of like how how might carry a piece of paper.
Regarding the grip of one's hand on a weapon, here's some Miyamoto Musashi for you: ". . . the thumb and forefinger grip lightly, the middle finger grips neither tightly nor loosely, while the fourth and little fingers grip tightly. There should be no slackness in the hand."
He counted the thumb as a finger, so that's ring finger and pinky/little finger, respectively.
