Now that I've had some time to get back to doing pages again...it takes me about a day to pencil a page, pending on the detail, number of panels(7 panels max), and how my pencil flow is for that day. If I'm really into it, I can cut down that time considerably.
It takes me less time than that to ink- especially if my pencils are clear.
I then spend a day coloring- used to be less time than that, but I started changing my patterns up and now that I've discovered texture brushes, I'm always trying to find a balance with that.
Lettering only takes me a number of hours; I spend the least amount of time on it- because I know EXACTLY what I want on the page in terms of lettering.
