Unfortunately as your comic gets older, your older pages will begin feeling more and more distant from your current style. I have pages that I drew earlier this year that are already looking stale to me, lol.
Something to keep in mind is that once you finish redrawing, there's a possibility that you'll have improved past the quality of your later chapters and could risk a dip in art quality. I've touched up older pages of mine and redrawn faces that look especially wonky, and I've struggled with the impulses to redraw my early pages too, but for consistency sake I think it's better to see a slow climb in quality than inconsistent quality from going back and forth
With your pages, there's definitely a feeling of skill improvement, but it still feels consistent enough to not interrupt reader flow. If you're worried about first time readers, something that could help would be to keep your cover page as up to date with your style as possible so people could get a better feel for the current style of the story.
