"Many times I was taught by different teachers. Things did not sink in. Sometimes the light bulb just goes off. I got it... It is a lifetime of learning. I still do not have a comfort zone yet. Never stop learning in your lifetime!"

Treat all light with one value, all dark with one value, then gradually add details. Adding details too early will weaken the structure."
