THis is so cool you make such fine art and great colors, but the proportions are not right, he looks like a teenager with a big head if you could enlarge his body to fit his head (or shrink his head) would be awesome
He's drawing the sword in a way that makes the blade "flat" to the surface of the ground. How do you mean the grip's wrong? Actually used reference for that part.
That doesn't fit his scabbard or the orientation of the crossguard, then. The way he's holding the grip also does not fit the orientation of the crossguard.
Look at some more references, the blade typically faces the same direction as the crossguard (in cases of the archetypal "two-prong" (for lack of a better term) crossguard), not perpendicular (as you have it). When a swordsman holds a hilt, he orients his hand so that his arm is parallel to the crossguard (after all, the point of the crossguard is to prevent a blade sliding down along yours and lopping off a hand).
Excellent job!
His sword seems... Extremely thin, though. Is he supposed to be drawing it horizontally? Because if so, the grip's fucked up.
