I caught Patrick just as he was leaving on my second last day of work, and shanghaied him into posing for a portrait picture.

In the work paradigm after the pandemic, I had settled on going into the office Mondays and Thursdays. Usually there were only half a dozen people there, and Patrick was always one of them.

Techniques-wise, I’m getting used to the new paper. It requires a layering of colour since it is so absorbent. With cartridge paper the grain is not open, so you can pick up previous water-paint with a wet brush. With this paper, the colour is pretty much fixed into the paper when you lay it down, so the necessary technique is to use many layers from lightest to darkest - and make no mistakes.

I’m not quite happy with the eyes. They need shadow and a subtle red that I haven’t mastered yet. But, to my credit, I think I’m getting better at mouths and lips, because nothing egregious jumps out as a flaw when you look at it - with a squint.
