Great beginning to season 2. I'll address my views of the comic in sections.
The comic itself was great. The thing I liked most of all about this specific comic is that you don't really have to know that much from season one to understand it. The flashback helped identify that specific important part which was helpful. It also added mystery as to what Terra Nuva actually knows. I think that the comic was perfect with size and details. It gave a good, small portion of the beginning of the story, setting up future events, and included a lot of details. Great work regarding story so far.
The graphics were quite nice in this comic although there are some things I want to address. The background you used, whether you created it or not, was a great choice. It's simple but it makes sense. The panel size is nice, not too big not too small. I like the simpler text, it looks good. I'm not sure how you'll work with it in certain situations such as when the background is the same color as the text but I'm sure you already have something planned. The flashback looked a little off but it was still recognizable as a flashback. The only reason it did was only because there aren't two Terra Nuva's. I think maybe adding something to the flashbacks might make it more recognizable such as desaturating the panel or adding a a white glow around the edges of the inside. This isn't necessary but I recommend doing something.
The main thing I am having an issue with is the reflection, it just doesn't look right. The reasoning for this is because I don't feel like the reflection matches the texture your character is on. Terra's reflection is blurred which means that it isn't a mirror since most typical mirrors will not blur a reflection. This means that either the floor is translucent or very shiny. Most materials that fall under this category would not create a reflection as opaque as that which makes it look very odd. My suggestion is to work on reflections. The reflection looks good, its just too opaque, maybe lowering the opacity of the reflection will make it look a little better. Other than those tiny details the rest of the comic looks great.
Anyway, good job on the comic and keep up the great work,
