Hey there! I have a website where I try out many different tools for drawing/ painting. I document everything on camera and cut it into a fast forward video with the appropriate piece of music in the background. For Coil subscribers I replace the music with my audio comments with tips and lessons learned. I am no professional. I just love drawing!
And here it is: Speedart by Kass
Sidenote: Your idea section got me thinking. I am no grafitti sprayer but I‘d like to bring so artpieces to the street. Banksy style. Maybe there is a way to connect both skillsets.
