Watercolor Portrait - w/c practice

Okay, here's another watercolor portrait - gotta get in there and try, ya know.  Although I do have some fairly successful w/c landscapes, this medium mostly eludes me in portrait work, even after studying with a fabulous w/c portrait painter, it's still a struggle - maybe because I do it so seldom. One should approach these challenges more than, say, once a year.  This one is 12 x 9" on cold press paper.  Thanks for stopping by!
