Orchid Painting - 15 x 22 inches

I have gone back to continue with the orchid watercolor painting.  It is done on a 15 x 22 inches sheet of cold press watercolor paper using Winsor and Newton Professional watercolor paint.  The background was done in a wash as the orchid area being blocked off by frisket.  Later on the orchid was painted in one by one using gradated wash over several layers.  I noticed that the background could be darker especially around the orchid.
