That's the problem: I can't. Leave a picture alone, that is. I may have spoiled at least one of the small and large studies that I posted about before, but as I always say to students, you have to go as far as you can and risk spoiling something, so you know when to rein it in the next time. For the top, smaller one, I used India ink and a fine nib to draw lots of spidery lines, before collaging some more poured acrylic shapes on top. For the bottom, larger picture, I drew freely with red airbrush pigment from the bottle, then went back in with a brush and the pen-nib again. This is where I may have gone too far.
