The artwork is quite good, especially in terms of colors and shading. The characters look kind of stiff, though, and it can be difficult to read their emotions at times.
I don't really like the font you're using. It doesn't seem completely suitable for a comic. You should go to blambot or some similar site to look for more comic-y-looking fonts.
Panel layout is mostly good in terms of variety and readability, except in 1.8 where the second and third panels are in serious danger of being read out of order. The eye prefers to cross borders that line up; the first and second panels on that page don't line up but the first and third panels do.
I can't really say anything definitive about the story, since there aren't enough pages so far to make any real judgment on that subject. All I can say right now is that I don't know what's going on, and I don't really feel compelled to find out. In fact, I'm not even completely sure yet what the premise is.
You also might want to add some space between the navigation buttons at the bottom, they look really cramped the way they are.
In summation, the best thing you can do right now is put a bit more life into the character artwork and work some kind of event into the story to keep readers interested. The first few pages had a good hook, but it lost a lot of its effectiveness after the apparent change in setting.
Oh, edit, Big Edit: Motion Effects. Your comic needs more motion effects. The lack of motion effects is what's causing the characters to look so stiff, so you should look into those.
