Well, I just finished reading it...
and if I'm brutally honest, those last couple of chapters felt rather rushed.
I'm not sure whether it was the fact that the story was taking scenes from the movie, or whether you were just eager to finish it off, but it felt like the story moved at an exceptionally fast pace. sometimes it can good to spare readers the details, and let them build their own picture of the world around the characters...but it just seemed TOO brief, too quick, at points.
But even so, a very solid fan fiction, and I'm happy I read it! It painted an interesting picture of Nala's time in Scar's reign, and the way you included Mheetu was interesting as well. Aside from the rushed feel of those last 2 or 3 chapters, I have little to fault in the fan fic...and I can get rather nit-picky when I want to

I can't wait to see what you have for us in the future!
