It's really good, but you did ask for advice. The only real advice I have is to reexamine the hands, they look kinda awkward.
The right hand for example:
- The thumb is missing. Looking at the length of the other thumb, if his thumb is extended you'd still see a piece of it on the other side of the hilt. If the thumb is gripping the hilt, it would be in front of the other fingers.
The left hand thumb is on the wrong side, it's be behind the other fingers.
P.S.
Your still a wayyyy better drawer than I am. My art major friends come to me when they want critiquing because I'm brutally honest. It's a double-edged sword though...
