no choice but to go digital, everything is much easy, cleaning it up, and make the inking look clean. and digital color is nice too, if you mess up, you can redo it. until it looks standard.
I'd have to second this honestly. there are webcomic artist out there that still do their comics the traditional way! if you know tsulala, she working on a webcomic called Devils Candy and that's done traditionally.
Never felt pressure to go digital. I decided to go digital; one of the things that I liked about going digital is when I zoom in during coloring, the linework stays solid for the most part. There seems to be something about the line quality of digital work that makes it pop out a little more than my traditional art(but I also have to admit- at the time when I made the jump to digital, I was inking traditionally using microns; I prefer using quill/nib & ink which can be messy at times).
My advice would be to go digital only if you want to. It shouldn't really have anything to say, and is pretty much a matter of preference. A good comic will always be a good comic regardless if it's made on paper or on a screen. In my opinion you can get very sharp and "popping" lines with traditional art too. And you won't necessary spend hours on cleanup. You can get good results if you treat your scanner good and tweak the settings a bit. If you only scan the lineart it is even easier if you have access to a scanner that has a lineart setting (almost no celanup at all). Can't really say much about scanning colors as I do the inking on paper and colors digital.
