Nice attention to details. I like this mainly because it gives a 'brawler' air to the knight. The bear arms scream confidence in his ability to block and parry, especially since the rest of him is protected. It leaves a sort of mind game: Does the opponent go for the easy draw of blood? Or do they try and read it as it is his only strength.
It makes a clear message: "Go on. Attack me. It'll be your last."
