I think that it is obvious: you want to say that apples are not oranges. And you do it in a unique way! Seriously, very impressive drawing. It may be weird but what really fascinates me is the red scribbles on white, to the left side of the subject; I am fascinated by such patterns, seemingly random, but holding a special harmony which you have to dig deep to expose. Or, you know, it could be just me!
It's not just you, it's also me and many more. I know what you mean, the stimulus of the seemingly random but inescapably significant for the human. A or the core of art. The unobvious is always more interesting than the obvious because there is nothing to discover left and the human is driven to search and seek.
Maybe that is the power of surrealism, to trigger these thoughts in the mind of the viewer. A mystery is always attractive, even if the artist himself does not know exactly what drives his designs and what the message of his art is.
