I really like the presentation of the boat in the foreground. I thought a little sinister Lord of the Rings appeal might work. Used the new Affinity Photo program to add clouds and use various tool to enhance.
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.
