I would suggest trying several tutorials (cell-shading, soft-shading, many other unnamed techniques) and then choosing what works best for you. After a while, you might find yourself creating your own techniques. Some people stick to the same technique for years, some experiment with other tools to find the workflow that suits their style best.
When I was in highschool, the anime-like cell-shading technique was really popular, almost everybody including me used it because it looked so nice and clean. Nowadays there is a tendency to stray away from the sterile digital feel - if you look at screenshots from various recent anime (I like http://randomc.net/ where many people blog many recent anime with screenshots), you can see that the designers like to get away from the simple cell-shading with various little details that make it feel organic (highlights on hair, gradients etc.).
We comic creators are not restricted by the coloring limitations of animation and I really love looking at comics done in various techniques (my hobby is trying to guess the process of creating other people use to make their comics and paintings
).
For my bachelor thesis on digital painting I did some video tutorials, this one has English subs so I'm posting it for inspiration: https://www.youtube.com/watch?v=KkZz6-6L6n4 - this technique may be harder to understand at first but it was one of my most favorite techniques for its efficiency and attractiveness (until I got Art Marker pen from Wacom which literally adds another dimension to the drawing process and speeds it up a lot).
But wasn't it really fun to color it? To me, painting is real joy - sometimes I feel I put quality over quantity too much
But what to do when it's so enjoyable!
For a while I have been thinking of making a comic tutorial series covering various aspects of comic-making (things that are not covered in Tapastic Guide) as well as art techniques, but I'm not sure people would be interested in it - would anyone welcome this?
... At the same time, for example one technique I use in the process for Trivia from Nature has been used by many creators (I can tell that) but I have never seen a tutorial for it so I hope it's not a national secret or something like that >_>
