Of course!
I mean, why wouldn't I?
Your past self can teach you a lot, specially if you're feeling lost and don't know the direction of what to take your comic to.
I usually re-read my comic once in a while, just to see how much my characters has evolved, what to think of when I thumbnail the next chapter and so on.
I forget sometimes what I have to explain further and what doesn't need anything.
Like... I was re-reading a comic I made 7 years ago and I'm impressed about my past self: BACKGROUNDS AND EXPERIMENTAL VIEWS.
I kid you not, I drew (awful) backgrounds, experimented a lot with scenes and it's something I get stuck with today, I feel as if I make very static and boring scenes so seeing my past self doing these terrible things kind of helped me thinking how I need to do that today!
... Where it's sees fit of course, that old comic was waaaaay over the top sometimes (but I enjoyed it still).
