"The creative mind hates standing still". (just made that up)
Pretty good. It is quite true, and is often a source of tension between an artist an the market/his audience. Because what the audience really want is to experience again what gave them pleasure in the first place.
But many artists get bored doing what they have already done once, they want to do something new. And the public might not like the new thing, so he gets angry.
Also the art dealer or other middle-man wants something predictable, otherwise it threatens his business.
Also, "to experience again what gave them pleasure in the first place" is of course not possible, since it already happened once, and if it's exactly the same, they'll normally be bored. So the challenge of "sequels" and series is to do the same, and yet something fresh. Not easy!
Talking about creativity, today I've gotten no entries at all in the BW Portrait photo competition... so your chances may be better than you think, and well, it's just for fun, go on.
