for me, it depends how much i care about the end product... i entered the webtoon contest earlier this year and was able to produce ~30 fully colored panels with... varying levels of finish every week. the way i normally blocked it out was a day and a half on drafting, 2-3 days lining, and 1-2 days coloring/ rendering. it was easiest for me to color and render in one phase just for timely reasons, but I can't say i'm the proudest of the outcome:
however, more polished comics generally take a bit longer, especially since i work by default in traditional- page style. normally about one full day (6-8 hrs work) for lines, and another two for color and render.
I upload to my series twice a week and usually do between 4-6 pages a week with 2-4 panels per page. It takes me roughly 2-5 hours to get from storyboard sketch to completed page, so around 30 hours per week. Some days are faster than others depending on the complexity of the scene or if I'm in the right creative mindset. I do sketch quite quickly and I use vector lines for my inking which makes cleaning up those lines faster. I also have a few tools that speed up the flat colouring part of the process. The canvas size I use in CSP is 7000 X 11000
Sketch/storyboard before scanning:
Finished page:
It´s good to see that I´m not alone when it comes to process and speed to finish a page. I used to be one of the rush through people and I feel like I got way slower during theyears. The quality of my pages is better now and I often ask myself why I rushed everythingso much when I was young. It has probably to do with that you want the end result wayfaster when you are a teenager and don´t have the patience.
Same thing but diff reasons...when I first started out I was just really amped and was cranking out pages- now my body hurts so I don't rip into pages like I used to; the quality for the most part is still the same, it's just that I don't have that energy that I used to when I first started.
