As I start to close in on the final stages of the drawing I also start working away from the photo reference. I can do this because the faces are established and it is really only the faces that need to look exactly as they do in the photo. Instead of painstakingly trying to copy every detail in the dress and bouquet it makes far more sense to improvise and follow my creative instinct. This I hope will make for a livelier drawing and will certainly speed up the process and therefore reduce the cost.
