Your work is wonderful. It's both beautiful and very serene.
I'm an watercolor painter myself, although, far from never wishing to compete with you. I have a question about technique, here, if you don't mind.
Those white lines that you use to highlight. I know of two ways to obtain them. I sometimes use (i'm sorry, i'm French, so I don't know the correct term in English), before I paint, a very thick, very sludgy substance and I let it dry, then once it's painted and dried again on top of it, you can rub it off. Or, I sometimes use simple white acrylic paint on top.
The acrylic thing would make more sence here because the lines are really really fine, but they merge so well with the bare paper (I can't seem to *see* white paint) that it looks like they're left blank. I hope I make sense. but yeah, I was wondering which technique you were using.
