I think you can have your style and use it when you want, the important thing is that the style fits the map.
To give a couple of examples, I'm also a pianist and i can recognize mozart from chopin or beethoven just after a couple of notes. All those great composer have their style and they used it for almost their works. But all them are well know like composer who created a so large and different type of music. For example Fantasie impromptou is really different than a nocturne n2, but both are written by chopin and it easy to understand that there's the same person behind both them.
But let me make an example with someone more related with paintings and the like
Leonardo was a genius, he did tons of different things, all of them, or almost all of them, have the same style....but he is agenius anyway. One of the greatest genius we had on this planet imo. That's wrong. No.
Picasso is another genius, he broke the rules of painting, creating something new. He was another genius imo. But he wasn't like leonardo, both them loved to experiment, but leonardo did his experiments changing the materials or the techniques but using all time his "hand", picasso did that changes all time with the style. In fact we know picasso had varius period (usually labelled with names of colors) in which he did totally different artworks.
A thing make one of them more a genius than the other? In my opinion no. Yes they're different but the genial mind behind them was the same.
So, up to you if you want to be a Leonardo or a picasso.....the important thing is that the style will fit the map.
