I worked on this a few hours this morning and the boy in the back's head is finished except for the final tiny touches once the rest of the painting is done. I've started the first washes on the boy in front as well as working out some of the first washes on the plaid coat. I was going quickly on the green coat to cover a lot of the white paper and started making mistakes I'll have to lift at the start of the next session. I decided to stop since I must be getting tired when I start making mistakes as my attention drifts. I'm loving the bright colours but some colours are harder to mix.
