Pretty happy with how this turned out for a first go at only using tiny circles to create tone and form.
Here's a link to what doing it looks like (thanks Bean!):
This is the start of this year's Senior Territorian Portrait - John Bermingham, who was a Maths teacher when I was at Centralian Senior College last time I was there, 10 years ago. He's still involved with the College, but as a regular relief teacher these days. And he's still running, much more seriously and competitively than me and quite the inspiration. Molly, the rescue dog is lovely - John used to take her in to College to befriend awkward teenagers.
