right ^ AAA characters begin first as tens, hundreds, maybe even thousands of quick sketches (and so does every other aspect of game art). Really rough and loose stuff. When it comes to art, it's suicide to try and get it right on the first go. You want to create as many possibilities as time allows and really focus in on nailing the essential feeling you want observer to get when they see your art/character. Only then do you put time into finishing the piece out. and really, really avoid that tendency to look through a magnifying glass. The details don't matter, especially with a little thumbnail image that's meant to grab attention.
