I'm a newbie in watercolor so here is a bit of practice. I used photos from the book "The Agile Rabbit Picture Atlas of Flowers" as reference. As you can see the first two are pretty crappy, but the rest is OK I think. Too bad the rose didn't scan properly, it looks very delicate in person.
Sakura Koi pan watercolors, Maimeri Venezia tubed watercolors, Pentel Aquash waterbrushes and regular brushes on A4 paper.
