Hi Sanjeev -- Always good to see a full hippo out in the open. You have handled the light quite well here , and colours look nice as well. SS is a bit too much here IMO, the framing is nice but i might come down slightly from the top for a more rectangular frame.
Hi Sanjeev, agree with Haseeb regarding the SS, but also your DoF. I might try a 16x9 format echoing the subjects landscape format. Is this a crop, I would try to tease some more detail out.
