How on earth you managed to get a water based paint to work so well with oil paints is beyond me! This is absolutely fantastic, the colours are wonderful and everything is so busy and exciting, it's cool. Awesome work.
The trick is, well, throw it all together! The oils I used were actually some sort of oil-hybrid that can be used with water. Very neat stuff because it is very easy to work with... well, it is easy for the stuff I want it to do which is stay wet for a day or so and then dry.
