Ninjon
His Channel is pretty new, however I can definitely recommend it.
The description of Jon’s Channel says he doesn’t take things in life to serious. But he is a seriously funny guy! On this channel you will find mostly tips and tricks on how to improve your painting. Do know that these tips and tricks are often packed in a rollercoaster of goofy sketches and hilarious jokes.
Jon is also the other half of the legendary podcast Trapped Under Plastic!
