Portrait Study

I want to do a bunch of portraits for practice so I decided to try this one in watercolor.  I was trying to get the correct look of the sitter, but I at some point, I just wanted to get a decent painting, so it isn't very 'exact' but it is close.  Sometimes I just can't figure out what it is I need to do to make it right.  Other times, just a tiny change makes all the difference.
