This is a litle too abstract for my taste. I'm not sure what I'm looking at or what you're trying to achieve with it. Your focus seems off, but that may be what you were trying to do...

First Impression: Nice colours and shapes. I like that a lot. The title makes it an illusion, and quite nicely too, but should it have to ? Should the image not be able to explain itself, and the title just support it?
I'm embarassed to say that I've never read the book! Because I'm missing the literary reference, I have no clue what the illusion is supposed to be. :( With that said, this is a nice abstract. The out of focus isn't adding anything to the image for me. But again, I'm missing the reference in any case. :)
