Hi Sanjeev -- I liked the way they are standing in ascending order or descending order ! Nice symmetry to it. I think you have also exposed well against the bright river which in turn is providing a nice feel to the whole scene . I might open the shadows slightly more as it is appearing to me a bit dark . Nice scene overall.
A really cool lineup of these giraffe against a beautiful backdrop. I don't think there's any chance of getting more symmetry out of 4 giraffe bulls than you got here
I would open up the darks just a tad as it feels a bit too contrasty/choked up in that tonal range?
