Ignorant person here. First time I've heard of Phil Noto, so thanks. :) I've seen quite a bit of (mostly) Japanese anime fan artist who do something like that: magulong sketch then color. It's pretty fun to do, mostly for study sketches but it works. :)

That's how I usually do mine (magulong sketch then color), but I'm trying to keep my freehand drawings cleaner now. Ang hirap hahaha

That makes two of us. I've only managed to somehow clean up my line art over the past couple of months. Weirdly enough, one of my first supposed jobs was to be a an assistant animator for a Toei subcontractor. You HAD to force yourself to draw clean lines, man.

True that. I discovered a technique that allows me better control while sketching with my fingers, but it's too darn tedious lol. No pain no gain, right? :)))

Haha. Harder to do, but the results are worth it. :D

Definitely. Kae, my constant partner-in-crime in all things art-related notices I've been cleaning up my line art lately. Weird thing is, I haven't been making a conscious effort of it. It just happened. :|
