What a great start!! I found a good flow to the structure and am genuinely interested to read more. A few moments are choppy, but I think that has to do with plot. The story moves along too quickly with minimal explanation, so it's a little hard to follow.
Also, the lack of description and imagery leaves a bit to be desired. I don't expect everything to be thoroughly spelled out to me, but because of the nature of the story (talking trees and dragons and a myriad of creatures), description of location and character is almost required. It's almost like listening to a movie instead of watching it. I want to root for the characters (or against them) but I can't do that if I don't know anything.
I think the story is compelling and I want to keep reading. I look forward to seeing what comes next!!!
