MrBeast's Long Way of Learning Digital Painting [C+C wanted]

[MrBeast]

Heya,
I am trying to paint every day in order to get good enough to be able to paint from my imagination. I have a few failures behind me already so :s My biggest issue is getting some good shape/volume down and I hope I can get over that with some reference painting.
