EEEEEEE...severe hints of JxS...-_-

Anyway, it seems okay, aside from said pairing I am trying not to notice. Not sure that even the adult Sissi would have that large a vocabulary, but it seems interesting.

As for Lyoko's new name, for some reason Terra Machina reminds me of a factory instead of a virtual world, but it's good.

I'm still completely in the dark of what is to happen next; I don't have any good guesses. If that's your intention, good job. If it's not...then uh oh. Although if it's not your intention, it's probably something on my part. -.-

Just please be careful not to stray too much from CL's original plot line. I understand that yes, this is the future and a new age, and much has changed since the end of the series, but straying too far from the usual plot and into unknown territory won't always keep your readers on track. You're doing a very good job with very good description, and you're making use of vocabulary, as well as staying true to Jeremie's character (as far as I can notice), but just be sure not to take the plot too far away from what most readers are comfortable with reading.

Just try to focus a bit more about the things we know most about, and what we're used to seeing and most familiar with: Lyoko/Terra Machina (now), and also Jeremie and the original characters. Inventing too many characters will have heads spinning...or mine, at least. x.x

As for the perspectives, I haven't been keeping track of them a lot, but just be sure not to use too many, because then it gets confusing.

But you've been doing a great job with detail and your plot, as well as staying true to a lot of the usual things, such as Jeremie's character. Keep up the good work.
