Hi, I hope you don;t mind - I've posted a workshop on your pic of the old car in Solitaire.
I copied two layers from the original image, desaturated the top layer and adjusted the curves a little to increase the desaturation effect subtly, then using the paintbrush tool in PS, I painted out the part of the image of the car to reveal the second layer below to bring out the original colour of the old car.
Hi Vikramdevrao.Your reworked image is much better after some work on the mountains. Another technique you could use to enhance the image is to layer a scenic view or sky scene over the original image and then paint out the overlaying part of the image to expose the underlying image of the elephants. I did a very quick workshop on your original image and used the backdrop from one of my photographs I had in storage. It's some mounts in the distance with a cloudy sky (cloudy sky because you don't have any strong shadows in your image.
I hope you see and understand what I've done here and please don;t take any offence.
