(Very) minor edit, demonstrating a way to show more the ear/nose. That's basically it, but HTH...



You still need to up the contrast too. I'll implement some of that stuff here, when I'm by a desktop pixel editor.

Those are not selective outlines. Here is how it should look:


I tried a sel-out acording the light source, but I like too how look my character with this kind of sel-out.
Coloured outlines are not the same thing as selective outlines. Selective outline is more like external AA, it works when you know that the background colour will always be darker than the character, and looks like noise against lighter backgrounds.

I just want to point out that that pixel of AA on the top left of the head (the curve) makes the head look pointy and changes the shape of what was originally intended. AA should never change the intended underlying shape (think of it as a theoretical shape that exists at a higher resolution), but only make the appearance smoother.
There are no ugly colours, only ugly combinations of colours.

This is a very important remark. A similar effect can happen when you systematically AAing "into" a shape, you favor the outside, it digs into the shape and reduce its apparent surface by a fraction of pixel. The opposite effect happens when antialias outside of the shape.
This looks like a lot of things to take into account at the same time, but on the upside, it means the AA step is an opportunity to fix some defects of disgracious lines (or borders beween two colored shapes), and volumes which are slightly too thick or too thin.
