Looks like a fairly hefty crop Trivedi. I would suggest a looser crop with more room at right and bottom of frame. Colours and exposure look great (perhaps the left leg could be desaturated a little) and looks pretty sharp where it counts:D
I like the pose. The leg color is a bit bright but the species does show that in the field. Is this a big crop? I see quite a bit of noise in the darks. You could do some selective noise reduction to reduce it. Also, a better head angle with the birds bill pointing more to the viewers left would improve this, but, it is what it is.
Thanks every one for your valuable suggestions. I will work on that. It's always good for the freshers like me to have such guidance, helps me in improving my skills further...... :)
