Over the neighbour's wall

This sunflower has just climbed high enough for me to get a shot of it.  It must be about eight feet tall now.  The morning was spent preparing a canvas and making a sketch for today's art group.  I have decided to switch  back to acrylics this week to paint a butterfly in foliage and I would like to make use of some vibrant colour.  I made a start in the afternoon and it is proving quite tricky.
