I've seen that you've taken a lot of the advice here to heart, well done. A couple of things that I think would make the presentation better, though, is smooth lineart. You've made them thicker and bolder, but they're still jagged. The sketchy lines sort of blend into the squiggly coloring. I think using smooth bold lines would help pop things out a bit.
You've also put gutters into the comic, but it looks like there's no rhyme or reason to the size of them. Gutters can be used to portray time. Small gutters illustrate a short passage of time, while larger gutters might portray the opposite. I tend to keep my gutters uniform, because, it's easiest, and I'm not an expert at the whole thing yet. At the very least, I think you should shrink the margins down a little bit, they're a little larger than they need to be right now, and it's actually disrupting the continuity of the page as a whole.
Finally, I've noticed a lot of tiny little panels throughout the comic. The balance of some of your pages is off. Large panels on top, tiny panels on the bottom. I'm not an professional artist, so I can't tell you why, but for some reason it bothers me.
My 2 cents!
