I am a fan of transitions. I believe that they allow for a nice balance in between scenes. The transition lets me build even more on my world. It allows me to show that the world is alive just as the characters are and helps me create a nice flow of tempo.
Ok I understand it can get frustrating if you are caught up and have to wait a day or two for the next page. Yet they make things much clearer as you read through the comic as a whole and when in in print enhances the book even more.
Transitions are key, especially in an epic, where we move in-between places and characters. They also help me move things along when I feel a scene is toooo long.
So in a nutshell, they are a moment to take a breath and wait for the rollorcoaster to begin again. Now back to tea and a little quiet creativity.
