My only thought about the writing style is that the tone is not held constant. Cliche and poetic are fine, they suggest a time before the media over saturation. Colloquial and modern is fine too, just because were describing dragons, jousts or an iron-age agrarian lifestyle doesn’t mean we need to use middle English (or our approximation of middle English). I think the author was going for a classical theme here and achieved that in the first few paragraphs. (After all what modern man would name his son Gale?)
I didn’t see the original, but what I read today seems like a solid post that achieves its goal (telling us the back story of the dragon scale). Also, for the most part, it sets a mood and a tone.
