My early iPhone finger paintings were loose and tentative, and that probably helped making them interesting. As time went by, I became more proficient and precise; in fact I’ve gone back to pretty much the kind of line I used most of my life. Only instead of tracing successive sketches over and over, I now just dim a Brushes layer and refine the lines by re-doing them on a new one. Everything done with my finger, still: removing intermediate tools from between my hand and the picture always felt like a step forward. Here’s a work-in-progress, an example of how my Recliner portraits get done.
