One thing I am gonna say about this fic that it is good. It has plot, and substance, but I think that you can actually expand it.

Give it more description and all. Make the surroundings seem more realistic.

Yeah, sure, you do have the basic narration needed for your readers to understand the current situation and stuffs like that, but I sort of felt that you...well, the way I would put it is that...I felt that the fic lacked feeling.

Like when it was with Sasuke and Sakura questioning Naruto. It could - should! - have been a very tense moment, where Naruto was on the edge, confused and don't really know what he should do. But I didn't get that kind of feeling at all as I read through.

But this fic of yours had several good points too. For one, I liked how Gaara was being so...forceful on Naruto, and I kind of...felt amused at how you portrayed Naruto as a timid fellow - so very different from his own self in the anime. But it was a refreshing one, because Naruto's appearance does remind me of a sweet, little child [holy...that blond kitsune really is going to kill me].

And Sasuke's and Sakura's interaction was good. Brilliant, really.

Not to mention that you knew your grounds well. It really came across as a scene from CSI and such, with you using all the professional jargons such as "rigor mortis" and stuffs.

I liked that. It showed that despite the lack of emotion, your fic had depth to it.

Keep it up, and perhaps...well, work on the emotion part. Good luck!
