This BrushKit for Krita raised from the lack of sharper edged brushes. But while I was creating a couple of brushes for my needs I started experimenting with settings like velocity, hue, value variation, etc. This in turn led to the creation of very interesting "experimental" brushes or brushes which can be used for effects, such as explosions, smoke, cosmic clouds, etc. Now with the release of Krita version 4.0.0 this brush set has been updated to integrate with the new excellent default set in to expand on upon it. Have a look inside if this is something that might interest you!
