Watercolour autumn leaves with Sennelier

This is a painting of autumn leaves using Sennelier paint on white Arches cold press paper, 140lb. The funniest thing, I can't quite remember how I did it. I think I drew a lot of leaf shapes, painted them vibrantly using two colours on each, then between them in black. Then, to give depth, I used transparent paint for leaf shapes over some of the black areas so that the black would show through. The detail and outlining of the leaves would be done by pen. Finally, a splash of various coloured paint over the entire painting.
