What about art trends?

In the nineties ultra realism was the thing, now impressionism is more popular, but what matters is what you do best. Whatever type of art you create best is what you should stick to, there are always clients for good art of all types.

Do you think you can paint in any style? Maybe you can and maybe you can't, but you shouldn't if you want to be remembered, choose a style and do it as well as you can.
