I recently got a copy of Botanical Illustration: The Next Ten Lessons: Colour and Composition by Valerie C. Price. I will admit that I wasn't paying enough attention when I ordered it and I didn't realise that this is actually the second book in the series – the first being Botanical Illustration: The First Ten Lessons.
I was slightly daunted by this, as I have no experience of botanical illustration whatsoever and I haven't used watercolours since I was a child. I'm definitely a hobbyist illustrator whose work has (so I'm told) a rather "naive" quality to it. Make of that what you will.
