It is not about how much time it takes to finish a painting. Sometimes it takes months, sometimes weeks and some painting just take a day. The key is to know when the painting is done. Each painting takes several layers. We put paint on top of paint to build in the texture and colors to recieve the desired effect. Some paintings require just a few layers, while others may be a complex application of compound layers. For me it is natural to know when the painting is done and when I am still missing something. Sometimes I will wait a few weeks to add the finishing touches. A good example is the hightlights in a particular detail. When the painting is completed it feels right. It is never how long I am painting the piece, it is knowing when all the details flow in perfect harmony.
