Not quite the same:  lots of (different) fine tuning with subtle and not so subtle color and line changes!

These are variations on a digital foil, each with considerable additional coloring by hand.  The foiled image was differently adjusted for brightness, saturation & contrast for printing.  Then I put in several hours of further work, taking each of the above images in slightly different directions.  This is easier to see in the larger view:  just select & move through the “lightbox” slideshow.
