The process of painting is complex. For me it's an instinctive process, yet so challenging intellectually, it can keep you awake at night.
The most crucial part of any work is when you get to the point where it could be finished but you take a massive risk with it. It's a gamble.
Rubbing the whole thing out. Turning the painting up-side-down and rethinking it. Putting it away for months because you can't bear to look at it, then letting it resurface for another phase.
I love that point. It could go either way but more often than not, even if it's a mistake, something better happens. The journey of a painting can take years, each layer from a different era, a different thought process. Layers are built up and worn away, integrated and blurred until finally you reach the final touch.
