A couple more hours painting on this today. I concentrated on the right eye blocking in the colour matching it with the reference image. It is going to be difficult in some areas because there is a glare on the glasses hiding some of the details that I'll have to duplicate.
I also repainted the background and corrected his outer hairline. I think the background will be left like that until the rest is finished and I decide if it needs any adjustments.
The yellow on his face is still just the undercoating but I know it's distracting. I can't cover it yet or it would get rid of my reference lines I will need later.
