Flower close up watercolor painting

This is a 11 x 15 inches watercolor painting of a close up of a flower.  Fisst a sketch was made on Arches cold press watercolor paper from a photograph.  Then watercolor paint was applied from the top left hand corner towards the lower right hand corner of the watercolor paper.  Each time the area was completely dried before the next are is painted.  Wet in wet technique as well as gradated wash is used.  Care is taken to not go over the wet area with too much water and watercolor pigment to create a run back.  I am experimenting the use of Paynes Grey to darker the shades and found that it creates very interesting blacks and if not too much is used, it would not turn the initial pigment into muddy color.
