Agree with Sabyasachi...
Tejas, Can you post any one of the photos? the one with negative exposure ? It must be looking lot better than this and more natural.
I mostly would prefer HDR for composition where subject is very far like series of hills, clouds, sunset etc.
Here subject is too close like trees are very near to camera. Its leading to loss of sharpness and reality.

As Sabyasachi said, unidirectional rays would be fantastic.
