As you well know, part of an artist’s [visual, musical, literary] job is to promote the *product* to make a living. That being the case, I think this artist [whether you like her work or not,] has made it. In spades.
Great. On the other hand, what shall it profit a man, if he shall gain the whole world, and lose his mind? I do seriously think this artist is disturbed. How is it even possible to fill up all that space without a unifying statement? Oh well, I guess the answer lies in simply downgrading the creator from artist to wall painter. He filled up space. That's all.
