Garth,
You put so much love into every detail and value that makes it a pleasure to study your painting. Doing things right is rewarding in it self.
The light is beautiful and you are right that the highlights had to be cool. I like the folds in the leather at the right side of the chair. That personal flower sort of balances the formal flag.
I wonder if the V - shape of the lines was intended to make some perspectively expression. I think it does create coherence and energy to the whole painting. It also seems that you have painted the background strokes to support the direction of the V - shape.
This, I would like to see in person and study. I think you are loosening up on your brushwork. Bravo.
Best, Allan
