What does it mean for a painter to paint in the manner of So-and-So or to actually imitate someone else? What's wrong with that? On the contrary, it's a good idea. You should constantly try to paint like someone else. But the thing is, you can't! You would like to. You try. But it turns out to be a botch... And it's at the very moment you make a botch of it that you're yourself.
