I just want to chime in and say that, for instance, when I'm browsing the PJ gallery looking at previews for art pieces, I may instantly know when a Big Brother or Tomic piece comes up, just by the preview. (And no, not because of the fancy 'PREVIEW' banner they attach.)
But because they adhere to drawing most things the same way, using the same methods and techniques. And, I think if they were to stop doing that and try new things, they'd start losing that style that makes them instantly recognizable. If either one of them did a very retro piece, I doubt I'd recognize it. But then again, I don't think I recognize any retro artist's styles.
What I'm wondering, based on this, is if it's worth losing your recognizable 'style' to go and do many different kinds of art, or to stay on with your most preferred and comfortable way of drawing, using those same methods and techniques and refining them, mastering them over time? I suppose the question can only be answered by one's self-motive to grow and experiment, and their need to be recognized.
I always feel that artists with an instantly recognizable style are more prominent to me, anyway.
