Very beautiful species with gorgeous color and excellent detail. It does look a tad over sharpened on my monitor though. Great BG, pose and eye contact. IMO it would be very nice in a vertical if you have sufficient canvas to Have more room at the bottom and less on the left. Even as a horizontal it would be good to have a little more canvas at the bottom. Congratulations on a beautiful image Santanu.
The comp looks fine to me, and agree the BG needs a bit of NR, which in turn will enhance this image. The colours look well exposed too. Well captured Santanu.
