Three drawings to use on a brochure

I am after three drawings of the three Ayurvedic doshas: kapha, pitta and vata. I would like the drawings to be colour, elegant, feminine and preferably watercolour or a similar soft look.

Ideally vata would be represented by some sort of water illustration, kapha with something botanical and pitta with fire.

The images will be printed on postcards where I explain the doshas, but also used on my website.
