Hmm... I'm not sure if you achieved the effect, because you selected and isolated the subject you wanted to be focused and blurred all the rest, when the right way to do it is to isolate a part of the middle and blurred the other parts.

Good source-pic choice (critical in this contest) and the enhanced color saturation is appropriate. However, the blurring is too extreme as well as too pervasive, especially on the rear end of the right-edge bus and the far edge of the left-side building which seem to be the same focal distance from the camera as the very-in-focus elements.

I agree with Dan. The blur effect is too strong; it's ideal for a romantic mood to the image, but for a tilt-shift it's better to reduce the effect to a soft level.

very nice work author...gl
