I work more in the novel end of things than the comic end, but your title did grab my attention. For a time, I was admin of a fairly popular Facebook page for public domain superheroes before I turned away from Facebook. I might have read all the original Fletcher Hanks stories.
As I mentioned in the Elevator Pitch thread, you hooked me, but only a niche audience has even heard of this guy. If that is your target audience, then you're off to a great start. If you want a larger audience, you should maybe cast a wider proverbial net.
Your artwork is astounding to me. Some might criticize it for being a little over-the-top, but to my mind, that is appropriate for this story. The characters are interesting thus far if a little lacking in diversity. The action depicted is clear. The decision to go strictly grayscale is -- okay. A few images, like that cover up there, I would have liked to have seen in maybe a monochromatic wash. I'm not really sure what I want because I'm not a visual art guy.
The dialog is above average.
The pacing is problematic. You have several pages in a row of (I'll call it) esoteric technobabble. It was sort of a chore to get through that part. You are setting the tone very well, but after it's been set, I don't see a reason to keep wallowing in the existential weirdness. I read the entire series to get caught up, taking me at least half an hour. The title character still has not appeared in the story. That's a problem. In Moby Dick, Ahab didn't appear for several chapters, but the others characters wouldn't stop dropping his name until he did show up, so Ahad appeared by proxy. Stardust is just plain late to his own comic.
Overall, I think it's fair to say that I am hooked and looking forward to the rest of the series.
