Tybee beach v2

I spent awhile tinkering with this last week and think on the whole it's a little better. 

Tybee beach

This is the first painting I've done in nearly a month, except little things in my sketchbook.  It's from a photo I took on vacation at Tybee Island in Georgia last summer.  I had an odd size frame that I picked up along the way somewhere--12x15 plus/minus--so I cut a piece of gatorboard and glued canvas to it.  Somehow not quite working but can't quite put my finger on what the problem is here.
