Trying to whip out a complete painting in 10 minutes. Came close, but at the end, couldn't connect to the CS server to use the Colorize feature... again!
I did the same thing HERE: https://steemit.com/hive-164671/@sidekickmatt/daredevil-speed-perspective-drawing-in-starbucks-with-color-fail
Made using Clip Studio Paint Pro on Microsoft Surface Pro 4. Including real time video of process, experimenting using colored brush swipes instead of doing lines in black ink. Maybe later I'll show phase 2, when I'm back home with stable non-public internet-ness.\
