Well, I did a few aboriginal snails all right, but also a good few trees with backgrounds in many shades of green. More precisely cobalt blue + aureolin yellow + burnt sienna. Amazing the range of colours that I managed to produce by varying amounts of just those three pigments. Hopefully I'll be able to reproduce the vibrancy and range when I start painting for good. This weekend, I'm just buying time before I set paintbrush to watercolour paper!
