Most artists do always seem to have a recognizable style, but some artists centralize their style so tightly that their art becomes kind of boring to viewers and simultaneously never perfect enough to the artist. I'm certain there is a comfy middle ground, but I'm guessing that area is what you fall into naturally without worrying about it. But maybe not.
What I've seen of your art has changed up and down a lot between really cool and not so cool, but for me that's made the cooler things more exciting.
