I like how the dof focus the attention on the detail of the tip of the flower. Lovely colours and the white spots does not bother me. I'm not 100% sure of the comp but I can't suggest something else as flower compositions are not my strong point.
Nagesh, for my taste, it's a little too OOF for me. Perhaps a tighter vertical crop would draw my attention to the point of the bud faster but as it is I find my eye wandering around not sure where to focus for quite awhile before landing on the bud tip. Also, it looks like you dropped your exposure by 1/3 (if I am reading your stats correctly) and I'm wondering why? The image feels a little underexposed to me.
I think a tighter crop and perhaps f5.6 would have given you a stronger image. You still could have razored in on the tip of the bud but had a bit more of the flower in focus to draw the eye to the edge.
Hey Nagesh, I agree on a tighter crop, and the white spots do bother me. I don't mind the DOF and like your point of focus. You could clone some green over the white.
