Remember when I used to paint things?
Moderately-quick painting based on this old unfinished piece
I had lying around. Made mostly as an excuse to paint clouds and auroras and stars and pine trees, my four favorite things in the natural world. I should probably document the steps used to create those auroras before I forget them ... basically it came down to making wavy ribbons with a painterly brush (shape and color dynamics turned on) -> duplicating the layer -> applying gaussian blur + soft light overlay to one layer and vertical motion blur to the original -> painting over the original layer in places with another painterly brush to define the ribbons a little better.
