Progress on "Zen Moment" watercolor

I had fun playing with this painting.  I tried miskit (mask) liquid over the fish like water reflection, then painted the water over it.  Then I took the mask off.  Maybe the painting over it should have been darker to show the masked area better.  Now I think I'm at the point where I could practise lifting out color, and lifting out highlights.  Maybe use a razor blade to get back to pure white paper ... and maybe a few dark shadows here and there ...
