I flatted the page pretty quickly earlier in the week before adding rendering over the last few days at work. I had about 10 to 30 minutes during my breaks and lunches giving me approximately 10 minutes per panel.
Kinda like PJ’s genius pomodoro technique (which breaks single tasks into 25 minute chunks) 10 minutes is a pretty perfect time limitation to set for a single panel, really keeps you focused.
PJ has collected his holiday comics along with a bunch of other strips on gumroad (it’s pay what you like) and I really enjoyed it!
I’ve uploaded my flats here if you wanna colour the page too.
