Here is a video I made regarding the art of quick sketch and some ways to set yourself up for a good session. Motivation is the name of the game and I have several illustrated in this video. The video is sped up so as not to bore you, and I apologize for the breathing of the camera. When the video footage is sped up it is really obvious that I am wearing a chest camera.
Thank you for watching. Pass this on if you find this instruction useful. and thank you again.
