I'm putzing along some more with my writing while I continue doodle-practice, I think I managed about 2k words yesterday in total.
I've made good progress in the last couple of weeks. I've combined all the scripting I've done for the various chapters of one of my series, just to gauge where I'm at:
Still have so long to go, but I'm encouraged that once my art skills are decent enough to start official art, I will have a solid/edited/finalized script to work off of. Then, other than random editing and continuity checks, it will just be about plugging away at the art. No guessing or trying to figure out how the story ought to unfold.
I should note I probably have doubled that amount but it's just filling out character sheets/random plots/world-building info/etc.
