One of the evening events at the concept art masterclass in Montréal was a speed painting battle.
Two artists sitting at large computers, their work projected on the screen to an energized audience of peers, attempted to illustrate an assigned theme within a 15 minute limit using Photoshop. No command Z, no history, no photos or photobashing. The loser of each round had to drink a tumbler of rum.
One of the competitors was Jeff Simpson, an artist at Ubisoft. He painted the theme "gravedigger."
I sat over to the side and painted him using watercolor. Although I wasn't competing in the battle, I stayed within the 15 minute limit also.
