Your eyes are very good. You saw your problem with the thicker outlines looking like a bad scan instead of pixel art and adressed it yourself. Too bad you had to use devil-worship to do it. Personally I enjoy the colored and weightened outlines step in that animation where you try to deal with it more than I do the selout, but I *do* give you that the selout version is better than the non-selout version at adressing the thick lines problem, and probably closer to the source art itself.
However, this is a different medium and you shouldn't try to copy how comic-arty stuff looks on it more than a bit. Bottom line is what promotes the medium most, and for that I'd go with the colored outlines, personally.
There's not much pixel-art level critique I can give you, I'd soften the interior-aa a bit more at places, there's still a bit of blurring, but otherwise, top job. Congrats.
