Honestly the real trap is getting stuck in the middle. Like you start with one layer for a sketch, then add a few for colors, then another for effects. Next thing you know you're sorting through twenty half-finished layers trying to find the one line you need to fix. It's not about having no rules or too many rules, it's about not having a clear plan before you start adding them. That messy middle ground is where the hours disappear.
Sometimes going wild with layers just kills the vibe, lol. I cranked out a whole comic page on one layer last week and it was way faster for me. Over-organizing can slow down the actual drawing part. For quick sketches or simple animation cleanup, a single layer keeps the workflow loose. It's more about what gets the job done without overthinking it.
