I don't know why you'd keep rebooting the same comic to be honest - it's not a good cycle to get caught up in and it's better to move on and make a new one in most cases rather than fixating on the one.
I do think the second batch looks better - you can see straight away that the art is way less muddy and more detailed, with much more interesting panels and composition.
Seriously though, I think rather than rebooting you should make a new comic. I think you could put all this improvement to good use that way! Telling the same story over and over is a bit unhealthy.
