Rose Painting

I have begun painting a large composition of a rose I have in my garden. This painting will be large  with five blooms and some buds. I have painted the first flower which was fully open and the oldest bloom of them all. I have used sennelier paints which are lovely to use. The first flower is finished and I have now stared a fresher bloom. I will draw the leaves after I have painted the roses. The paper is white, I have trouble photographing my paintings.
