|Soft Gel with Green-Blue Interference|
Right: On a piece of white HDPE (High Density Polyethylene) I have painted swirls of soft gel mixed with interference blue fluid acrylic. I really can't see the blue at all, at this point. I hope it is not too subtle. These skins will be applied to an underlying layer of blue, to give the appearance of clouds. One meaning of pneuma is air, or breath.
After that, who knows? The pieces will have to suggest their next steps.
