Had to do something for Easter (and continue to feed the binge; lol). Liking the distance transform for making more flowing placement of dots. Was just blending but now using Difference layer property which, at least with this bunny, gives sharper results. I did add some caustic/ reflections, but used secret sauce (i.e, third party PS plugin; lol) for that effect.
