Hey Arijit,
Comp and light look VG although as usual.....a slight angle towards us would have been preferable. As presented, I feel there is just too much space around the BF. A crop of about 1/2 the space below and right would work best for me.....and you may want to run another round of Noise reduction on the BG as a final touch. Just some options for you to explore. Nice job overall.
Thanks for the inputs. Well I can do both the crop and the NR. This sensor holds up to crops very very well. Next time round will try to shoot at a slight angle.
Hi Arijit and welcome to Macro! A 300 mm makes a very good "macro" lens for butterflies and the sharpness of your subject and the pleasantly blurred background illustrates this. Nice light and a good eye-level shooting angle. I would agree that the image would be even stronger if the subject was facing slightly toward us. The tighter crop suggested by Roman will also take the image up a notch. You're on the right track and I hope to see more of your work.
