I respectfully disagree that its the galleries that stifle creativity (yes you spelled it correctly

). I remain true to my "style' but there can be variations within it. Staying creative also involves taking risks, and trying to do a particular technique or subject that you haven't done before and developing the technique or subject further. Its growth, its your style coming into its own. That said, if an artist WANTS to explore different styles, well then go for it! It may be your niche that you've yet discovered!
