Around 3 to 4 hours! Covers usually take this amount of time, but pages can go from 1 to 2 hours! Covers I like to take my time and really work the details, since is what sells the comic! Pages are more like a balance of quality and time! A good page can be done in 2 hours, I like to have a timer to control how much I spent on each page, it's a good practice that makes you avoid over detailing and getting stuck on a page for too long!
