Hi Sabyasachi,
Very nice colors and good placement of the sun here. For me, there is a bit too much base so a crop of about 1/2 the base black and perhaps a hair off the top will help strengthen the comp. You mat also want to lighten this just a touch, as i find the RH side a bit dark.....a final touch would be to also try Robert's LCE adjustment using unsharp mask....20/25/0 should give it a bit of pop to make the colors sing! Nicely composed and very nice job using the tree as a framing element.
