Your 30 mins speed paints are pretty damn good :-) Don't expect less to be honest.
I'm not so strict with the time, 30mins, 60mins and 90mins for me are good ranges for speed paints. Any longer you are in iterate, refine and polish territory :D
Was thinking a speed painting contest here would make a ton of sense....
Yes I'd definitely prefer more than 30 minutes too, sometimes I'd cheat right at the end and keep fiddling for a couple minutes... naughty naughty. :)
Yes a speed painting contest would be very interesting, I must think about it, haven't made any contests yet, hmmmm...
