Good Art vs. Bad Art.

What is an art? Common definition says an art is a work produced by skills and imaginations typically expressed in a visual form. From the definition, an art should be able to express itself in order to be a good art. It should have the ability to attract the audience and express itself in such a way that there is no need of further details. This is where the creativity of an artist functions. In my opinion a good art can be anything creatively produced which can express itself and has a meaning behind the visual presentation.

Now talking about bad art, as I said on my first paragraph that an art should have the ability to express itself which directly shows the properties of a bad art. So an art which fails to express itself to the audience and the audience doesn't have any sense of what the art tries to express which in my opinion is a bad art.
  

In my opinion this is an example of good art. This art from my point of view says a story of a girl who is a master in solving Rubik's cube.

This picture is an example of bad art in my opinion. I didn't understand what the artist was trying to express.
