I usually spend about 8 to 15 hours to draw an episode... But I'm working faster these days because I'm kind of getting used to my style and digital art in general
Also the thing is that sometimes after finishing the colors, I add or remove a panel because I don't like the final result and I lose many time by doing this
It takes me about 2 or 3 days to make a comic but I often draw the weekends so it takes me some times to upload an episode
