I read all of this of people working so fast (seriously, MAJOR KUDOS for you guys!) but Cosmic Fish ranges from 42-52 pages and it takes me about 2 days to make a page (be it work or just working on details) at around 8 hours per day.
so it takes me an average of 4-5 months, frustratingly hahaha...
Some days I work faster, it really depends where the story is at or the coloring method I use.
