Over 10-12 hours per page, which is way too much for the results on my opinion. My aim, though, is not to reduce the time to make a page, but rather to improve the result obtained in 10 hours.
I have a highly seasonal job. During these past 9 months, I only managed to draw 10 pages, which is quite a depressing rate. In the low season (coming now), I draw almost a page a day. Doing absolutely nothing else than drawing, sleeping and eating.
