Good question. I've known for some years that I am most comfortable in the mode I'm currently in (vintage with an edge), but I keep feeling tugged to go in another direction. Every time I try a different direction the work comes out contrived or just plain bad. So I would say that on one hand I do know who I am as an artist and I know my point of view. On the other, I really think there's much more room to grow.
I am of the opinion, though, that in order to be a GOOD artist, if not great, you must always be willing to grow, play, experiment, try different things, and so on. Otherwise you become stale
