Nice shot. I like the extreme vingetting, it works well here. Minor little quibble, but the shadow obscuring some of the petals at the bottom right of the flower is a tad distracting. Minor quibble as I said ;-)

I like the sharpness of this flower. The colour are pretty but I would liked them more saturated.

Lovely flower shot. The central composition works very well with the symmetry, the technique is good, has good impact and is good quality. Not massively original, perhaps, but I really like it.
