If you want to draw heaps of somewhat-stylized asters in a few strokes- this catalog is for you!
- "asters set color"- brush already have color. You can change it with tonal correction/gradient maps.
- Stem brush mixes main color with sub color a bit, so you can use sub color to make stems fit the background/lighting better.
- You can change spread and density of flowers to fit your needs by toggling "brush size"and "particle size" settings.
I think the easiest way to use it is to draw flowers first and then add stems on a new layer underneath the flowers.
