I especially liked Alan's Art History Brush (AHB) interpretation above. Once again he inspired me to experiment a bit more with it...
Rough workflow:
* Multiple layers of AHB strokes using different brush styles, e.g., Spatter, Chalk, Dry Brush, Rolled Terry towel, etc.,
* Tried different brush diameters (3-8 for detail, 20-40 for large/fill-in areas), Daub and Tight Short
* Brushes Palette: Hue and Brightness jitter setting tweaks yielded some interesting results.
* Merged visible, sharpened, painted some more, sharpened some more -- you get the idea.
* To get some edge detail: Applied Smart Blur > Edge Only to a copy of BG. Image > Adjustments > Invert. Applied Stylize > Diffuse > Anisotropic to soften edges a bit. Added Hide All layer mask and airbrushed with white to reveal some edge detail.
*GREAT* pic to work with.
