“Best” depends on several things, main one being end-use – do you intend this for a game? Rigging/animation? That includes facial expression? Just practicing? If so, what are you practicing? You said low-poly, are you trying to keep this below a specific number? If so, what is it? You said “clean”, that often (but not always) means “good” all-quads topology (no poles less than 3 or greater than 5, no poles on creased, tightly curved, or transition-between-flat-&-curved areas, loops follow function, even-as-feasible polygon distribution, etc) – has some particular challenges with that face, especially if you’re trying to keep the polycount low.
In your last topic there were some vids recommended, the one about making the fox character seems like what you’re looking for here, but isn’t useful topology for a lot of purposes. What’s your goal?
