Daredevil Speed Perspective Drawing in Starbucks with Color Fail

Stopped at a Starbucks and thought I would make a quick speed drawing of daredevil. Trying to work on my perspective sketching. I was also taking a video of my Surface screen to show the process and was trying for a 10 minute drawing. Unfortunately my free Wi-Fi connection failed so I couldn't connect to the Clip Studio server to run the autocolor, so now it's a black and white drawing.

Here's the video for those of you with extreme patience. When I get back home to stable internet maybe I'll show the quirky autocolor process that I use for these speed drawings.
