This is.... there are no other words for it...... really pretty. The tones, the almost perfect symmetry, the colours, the focus, the composition - all very good.
My only criticisms are from a symmetrical aspect the bottom of the flower is off kilter, which is a shame. Also, I feel the shot could have been straighter. It seems to be balanced more heavily on the left.
However, this is still an excellent shot, which deserves a top score.
