I like your use of DOF. Usually I would want more sharpness, but this works, perhaps because of the intense colors. Is the saturation a result of the film, or did you bump it some in post processing? This is really nice, Aiman!
This is my favourite photo of your flower studies so far. I think flower macros with shallow DOF are about pinpointing just the right area of a flower. Here I see two beautiful shapes trying to break free from the blue (the one on the left looks like an eagle about to fly away). The rest of the flower provides wonderful colour and strong lines that add to the interest without detracting from the primary focus.
