A half hour per day; lunch time sketching is a slow process. I take a photo each day just in case I mess the whole thing up and have to trash it!
I am getting more ambitious with my lunchtime sketching, this time I used real watercolour paper, taped onto board. The painting took three lunch breaks to complete also and not the usual one. I am trying to be more patient when I paint, I think three hours is a long time while professional portrait artists can spend one hundred hours easily on just one painting, I have room to improve my level of patience.
A nice nice video that offers tips on how to paint trees with watercolours.

Oh, I like this artist’s technique too! I’ll have to check out more of his work later, he seems to be very good.
