The flowers being out of focus takes the out of the idea. Also, I would have prefered this in color. There's just something not right about food (and flowers) without color.
I don't get what is opposite about the elements in this photo. The still life of the fruit looks very nice, but the out of focus flowers really detract from this image. If the flowers are an important element in the photo (as I suspect from the title) I would prefer to see them in focus and more than 1/4 of the way into the frame. As it is right now, it feels very unbalanced- the eye is drawn all the way to the left of the photo and out of the frame.
The fruit are nice and clear but I find myself distrated by the blurry flowers on the right. The speia tone works well. I'm not sure how this relates to opposites though...
On it's own the bowl with fruit would make and interesting still=life study. There's good lighting there with enough detail in the shadow. The out-of-focus flowers are not a good addition to the composition.
