I really like this concept and your character designs are spot on. I'm excited to see where you take this story and you haven't even introduced Edward yet. At this point I'd just read a comic about Leviathan lol.
The only feedback I have is to keep an eye on your text bubbles. There are some consistency issues in what you've published so far. In a couple places the edges of your text bubbles get cut off. In these spots it looks like maybe the file you uploaded was too wide. There's another text bubble that has the purple texture behind it bleeding in/overlapping the bubble itself. This doesn't look intentional so I'm assuming it was an accident. There are one or two other bubbles where the font isn't consistent, but maybe this is just a design choice.
Making a comic is hard and so far you are doing an awesome job! I subscribed and I can't wait to read more!
