about the colour it's to light, the original color is by default light colour changing it into blue hmm well it stayed a bit to light for a blue colour..I don't know how to explain but it doesnt look quite right

very difficult base to change colour in my opinion especialy because the back of the car is blured that make the whole thing of changing colour a lot harder

Colour is too light and doesn't look real..try playing with brightness of the desaturated base to make it darker and than adding the colour layer maybe it will help
