This is looking really promising so far. The smaller reflections in the body will make or break it so be careful. Don't be scared of making them sharper. The rest goes for parts of the body as I can already see that the front bumper is getting blurry.
Also the window reflections don't match the environment, you might get away with just removing the blue/green hue from them or maybe turning it to white.
