Bar-Mitzvah's and Bat-Mitzvah's are another avenue that party caricaturists work at. I drew caricatures in Calgary at this one about three weeks ago. These are fun for me, though I'm working on a new style when I get some new pens in where I can quickly draw a small body that I've also been working on. Bodies that will only take about a minute and a half or so. At the above Bat-Mitzvah, I could only draw the head and shoulders as there were a few hundred people attending.
