Trees - Uluru

These were drawn using a fairly thick mix of ultramarine and burnt umber watercolours, poured into an Aquash Brush (the paint doesn't flow as smoothly as I expected, but it does produce a nice calligraphic effect - But now that I've read the instructions, I realise I was using them wrong - you're supposed to just put water in them, and apply watercolour with a watercolour pencil or watercolour pans - perfect for travelling)
