With the shardbearer holding his sword behind his head and Kaladin just standing there with his knife there isn't much action to show.
Not sure how 'true to source' it is, but when I picture that scene I see the Shardbearer swinging is sword low (and in a slight crouch in order to do so) with Kaldadin jumping over the blade and thrusting is knife forward into the Shardbearer's eye. Also I picture the knife in Kaldadin's left hand as he was holding a spear in his right, but again I don't know how true to source that is. I would sketch something up for you, but (A) I am horrible with computer art and (B) my camera is on the fritz. Also I don't partiuclarly like the idea of sharing my art with the whole world as I don't feel I am as good at it as most of my friends seem to think I am (though some of them are very good at it).
I read the scene about a dozen times, trying to figure out how to make it look. I'm pretty sure that, in a technical sense, my drawing is completely accurate, except that Kaladin should have a helmet on. However, just because everything I did is right, doesn't mean it couldn't be *more* right another way.
"The Shardbearer brought his weapon around as Kaladin skidded to a stop and flung his arm to the side,slamming the spearhead right in the Shardbearer‘s visor slit."
If he skidded to a stop, I'm assuming his feet are planted as he attacks. The shardbearer hasn't yet swung, and is about to as he takes the spear point to the eye. I don't remember any specifications of which hand he should be holding it with, I was just thinking that if he threw the knife right handed (may or may not be true) he would have had at least his right hand free to snag the falling spearhead.
However, although I'm happy with the technical details and perhaps the accuracy of the drawing, there's a lot I'd like to be better :/
