Just some jumbled early morning thoughts! Possibly more than you asked for. Everything's my humble opinion.
For the navigation buttons, I think the "in this story" text on the side buttons, and the "in story" text beneath the comic page, are redundant. It's just more text to read for no reason -- plus, with the side buttons, the extra text pushes the "Latest Comics" info down so it's off the screen. These links should be visible right away to readers arriving on your landing page without having to scroll down, since it's the "hub" that redirects to all comics, yes? I'd actually question whether the side navigation is necessary since this is repeated beneath the current comic page.
When I hover my mouse pointer over STORIES only Bounty Bunny and Sol Invictus list/drop down. I expected these links to take me right to the latest page for each comic, but they take me to story synopsis and cast pages instead. I'm wondering if STORIES ought to logically take me to the current pages for each comic, and the synopsis/cast pages ought to be linked under ABOUT (together with a link to your current "about Ink Proof Cannon" page). Yeah I realize this is your choice! I'm just saying what would appear more logical to me, a simple reader from the Shire.
Comic title banners! Methinks the current story, i.e. the latest comic displaying on the landing page, ought to have its own title banner above the comic page, no? I appreciate this info displays as alt text but a color banner for each comic could really crank up the site's drab appearance (sorry!).
On a similar note, must everything be B/W/grey? Your Ink Proof Cannon title, I'd switch this to color, probably gold/yellow, so it zings. Ditto the STORIES... ABOUT... ARCHIVE text, i.e. switch the mouse pointer hover color (yellow) to become the default color so they stand out more.
Right now it's not a question of whether or not I *like* the comics, it's how you can even make me aware (when I hit your landing page) that there's *more* than 1 comic to read, and how to *get* to them that matters.
Hope it helps! Ignore if it doesn't.
