Sorry it's taken me so long to send in this critique, life's been hectic! I am trying to catch up now though . . .
Having said that, I agree with the above people that the more I read, the more your story draws me in, which is a great sign!
I really only have two comments on this submission:
One: While I liked the description of the magic and the discovery of what was wrong with the protagonists, I felt that the solution was a little too easily had. I'm not saying that the scene was done bad, but I think you could do it better, use it as an opportunity to build tension, etc. In short, make them work for discovering what is wrong.
Two: And I think I've mentioned this before. The characters we are reading about are completely inhuman. They have tails and snouts, scales, etc. I'm unsure if they have other features like horns, ridges, etc. (which might just be that I've been AFK for more then a week now). My point is, they aren't human, and I think you should play that up. Have their tails wag when they are happy, stand out straight when they are tense, and have the characters notice these things. If they don't do those thing (ie. have good self control) have them notice that too.
If these guys are lizard-like, then go research the signs lizards use when attacking mates, when threatening away predators, competition, etc. Then make up a few of your own.
I did like how their eyes changed color to show moods, I want more!
Good work!
