My view of the way I use various approaches is that it is very calculated and thought out.
Perhaps the best way to describe it is that I work as a writer.
I'm telling a story. As a writer would carefully consider a choice in words, and syntax, and dialogue style, or if third person, or first person is a best way to tell the story... I do that, but I also use the visuals as another tool of the writing, and I consider what is the best visual way to communicate those tonalities for that particular story in the same way that I edit the word choice.
So often, I draw things in several ways, and consider several visual approaches before narrowing that down to the precise visual communication.
So does it bubble?
Maybe on the first draft. And then I do several other drafts of the writing and the art as I fine-tune the integration between them.
Much of what I do is probably more like film editing than bubbling.
There is perhaps quite a bit of bubbling uncontained at the beginning, and then I cut and shape and sculpt and redo that afterword.
My writing philosophy is that on the FIRST draft, write, write, write, everything that occurs to you on pure instinct - do NOT censor yourself. Do not second guess the writing. You do not have objectivity about that on a first draft. Just get out every single idea and instinct that you have.
And THEN -
On the NEXT dozen drafts -
Re-think, re-shape, try it in a different order, try it in different persons, different characters, change the words, slim it down, cut and edit and add and move around, etc. until you sculpt all that naked energy and raw idea into something very precise that hits the reader in the brain in just the precise spot, like you are destroying the Death Star.
