Finished my first Munny last night. Made him into a tiger. Did most of the painting with my airbrush, then did the stripes by hand. Was going to paint the eyes in until I looked at it as is and decided not to mess with it anymore.
Since I do modelling and have an airbrush I used enamel paints. That's probably not a good idea unless you've used them before. Most people seem to use acrylics.
