Study for a painting

I'm working out an idea that I have in my head and to do so needed the help of a model.  I have always used friends and family but am running out of people I know who are willing to pose or be photographed, so the time has come to go up a level to hiring a model.  This morning she arrived for a short photographic session.  The weather was perfect and so was the lighting so we wandered in the garden and field and I got some good photos to work from. This girl has beautiful Celtic colouring pale freckled skin and light titian hair so she should be wonderful to paint. The sun shining through her hair gave her skin a warm reflection too.

The concept that is in my head may not work but there is only one way to find out isn't there?   I sat down late this afternoon to do a small study from one of images that I narrowed my choice down to.  The final piece will be in watercolour and may be layered - or I think so at this stage, but you know how things change sometimes.  I used my kraft paper sketchbook with charcoal and white pencil to put down form and base values so I could see if this would work as a larger piece.  And I think it will.
