I'm going to do 2hour speed paintings, following this one.
Just like this one, I'll try to: work from colour on up, on one layer, without saturation, colour correction and layer effects, texture brushes, etc.. Stop after or before 2 hours. In addition trying to: explore angles and tell something in the picture.
The idea started as: "must paint something with a tropic island".
Inspired by Jesse van Dijk's Indigo concept, I think though.
