i found a group that does an online 12 hour speed paint event every sunday: https://www.facebook.com/concepteez. i highly recommend it. especially for beginners.
i managed to catch the last couple of rounds. 50 min each.
vehicle round - hovering bee. not bad!
there was a 15 min break between rounds so i tried to detail it some more. meh...
weapon round - gas powered weapon. fun! :)
portrait round - luminous clown. tough round.
