I second this!!
I don't draw, but letter my comics, and oh me oh my. I knew about bubble positioning and stuff, but never really paid attention to how people position the words inside a bubble before actually having to do it!! It's one of those ''got to feel it in your skin'' stuff.
I also think, as a beginner, I underestimated how difficult it is to pace your scenes in the space you stablish yourself. I like to work in definite spaces, so there's almost always this lack or excess of space and you got to crack your head open to make it work, to fit all in. It's a pretty nice kind of puzzle, though!
