Do appearances play a big role in your stories? How you go about designing your characters.

A big role? Not generally.

Since I like to write a lot of action sequences, my main characters are usually pretty fit so that they can reasonably handle the torture I like to put them through. A character of mine is usually only exceptionally good looking if there’s some kind of story construction behind it (or if my target audience expects/demands it.) The same goes for a character that isn’t attractive.

My view on the issue is that characters all start in the same place “average” and according to the story’s need, should be adjusted. I try not to waste time on descriptions that aren’t going to be used later on, so I generally let the audience fill in the gaps with their own defaults, which likely makes the character more likable in the long run.

At some point, I almost always draw my characters. This is when I work out details such as particular hair-style, specific fashion notes, certain facial features and body proportions. Then, depending on what I come up with there, I can go back and edit written details later.
