Thank you Sabyasachi. I agree with your comments. I have quite a few images of this animal. This one wasn't my favorite or what I think was the best image. I liked it because of it's in your face posture but I was also disappointed in the fact that the animals eyes aren't easily discernible.
Michael,
Moved this as an independent thread. I feel it is better to show different images on separate threads so that people can critique better.
This image gives an idea about the animal, at least to people like us who are new to this species. The framing is a bit tight. A bit of more space at the top and front would be nice. Is this a full frame image? A little bit sharpening on the head will be good as well. I wonder how you guys hand hold the 600mm. :D
