One four panel Free Falling page takes approximately 3 hours to fully produce. It varies heavily, depending on how much I have to draw + my emotional drive each day.
About 30 minutes. (copy pasted panels, one character to draw)

2-3 hours. (panels are subdivided, have to look at references for drawing non-main characters)

3-4 hours. (lots of characters to ink + color + need references, more time needed to plan out composition + actions of several subdivided panels)

I typically make 6 pages a week. Each page is (usually) 4 4:3 panels.
On average, writing all 6 takes 2 hours. Storyboarding 3 hours. Ink/color/detailing 2 hours for each page. Revisions/finalizing is 2 hours.
