I love the premise of this. The concept of a goblin striving earnestly to be a really good Knight is hilarious. If I am unflinchingly honest, though, I don't think this story lived up to the premise. I was expecting more of a farce, or at least some comedy arising from how a goblin, with a very different cultural perspective, understands the demands of knighthood and chivalry. (You had the beginnings of this, such as with Shinsplint emphasizing scent in how he perceives the world, but it didn't go anywhere.) There isn't even a great deal of slapstick going on (which, again, a nine-men-v-one-goblin fight seems to invite). Basically I was expecting to laugh, and I only kinda chuckled.
Again, it's a great premise, and the story is well-written from a technical standpoint. I'd suggest that you rework it to take better advantage of the unique and entertaining possibilities available with the idea of a goblin striving for knighthood.
