Using selective desaturation is a tricky thing. In this case, it almost makes it look like a collage, which could dilute the impact of the car's location.
However, without seeing the original, it's hard to judge if anything else would work better. Other things you might try are fading the background color (going to pale pastels or maybe sepia-toning) instead of going to pure B+W, or reversing the effect and having the landscape in color and the car desaturated.
I really like the overall idea and composition; terrific landscape and clouds. I hope you took a few shots without the car too : ) |
