Mike,

Perhaps this belongs in the Techniques section, but have you thought about going after your fine edges in a negative fashion, rather than a positive one?

I find that the only way I can get tiny, fine crisp edges is by "cutting" them away. I'll try to explain (better just to show).

If, for example, the finest line I need is on the lash line, I take the darkest (but right-hued) value pastel and place a line. It's way too thick, but it doesn't matter because I then take the adjacent value/color, and cut into the line I've just placed, so the remaining area is right. I then move outward in concentric areas, cutting away the line or shape placed just before. I have never been successful in trying to place crisp lines with a positive approach.

Please let me know if this is unclear.
