Hey Ovidiu,
I think this would be even stronger with a crop off the top and right...eliminating some of the brighter areas of the flower and keeping the focus on the bug. Nice DOF and light and the bug looks nice and sharp where it needs to be.
I think Roman nailed it - the repost really puts the emphasis on the insect! Lovely image, Ovidiu - it's a wonderful play of textures and opposites here.
