DON'T GO BACK
The final decision is, obviously, yours to make - if you're preparing to print something, and you see a hideous inking error on page three, sure, fix it - but do NOT get stuck in re-drawing earlier pages. It is a terrible tar-pit to get stuck in, and is a really fast way to kill off any enthusiasm you might have for your story.
Because this:
... is going to ge true when you reach page 200 as well. By then, page 100 is going to look very different from your current pages.
That's how artistic development works. We're always learning, we're always changing, we're always going to be drawing slightly differently tomorrow than we are today. And if you keep going back to "fix" the old stuff, you're not going to have time to draw new stuff.
Basically what I'm saying is no. I really don't think you should.
