As always, love your style of drawing, here are some little things that I would change, but aren't really important: The archer should have a bracelet, not a gauntles, since you need your bare hands for using a bow efficiently, second, the warrior looks generical, is he a hero or a simple minion of the castle? because he looks like a big minion, or an enemy, not a hero you want to play as. That's pretty much all i've sseen which wasn't completly ok with your drawings, then again, they still look fantastic.
