Firstly there was Matt K's beautiful minmalism:

However the lack of symmetry in this photo tipped it out of favour, despite the rich blacks and stunning lines. This has to be one of the standout images from Matt's recent postings.
Next there was Greg's almost painted reed.

In both orientations it has great detail and a visual feast of tones and contrast.
However it has to be Chris K's Robber Fly that stole the show for me. Some may want more DOF, others may dislike the subject matter. But this image proves that once you get the eye's in focus (and the many eyes in this case) then the rest of the image falls into place. I am always partial to a good macro and this has great light and a lovely red-pink background that only accentuates the details.

Congrats Chris!
