Alright, as example I take the front/rear arch
You have multiple colours and tones, which is a (very) good thing. But they dont blend smooth enough. Also, the arches dont look well shaped, it looks a bit wobbly. Thats because the different tones/colours dont blend the same into the side of the car. What you can do is to create a layer of the side of the car and make a new layer with the arch. But make the arches 'bigger' and then delete the part of the arch that you dont need with the eraser tool. The result will be that the whole arch blends better into the side of the car and all tones/colours blend the same.
Combine your brushing more with the pentool. Suggested that also to Nordic Man, he said it works better and make the brushing looks smoother indeed.

Hope you'll understand

whow stunning , my feeling is could find even better rims but , damnn this looks sick

Rims look great from a shadow highlight point of view, as well as design. The design fits really well with the rest of the car I think. My only issue with them are that they are a bit wobly sort of, they are not completly round. Might have happened during the brush or something like that. Could be fixed by going back using a circular path and adding that around, and filling the area.

Other then that just keep going, will turn out sweet, but sweeter with an actual bg! Hehe. I am just gonna keep mentioning that untill:
1. You do change it
2. Finnish with a truly amazing result

Cheers!

Impressive stuff so far. Lovely bg environment

wow one of your best so far! Truely getting closer and closer! Its fun to see the steps haha

keep it up dude!

sweet update, i like the style of the rims, keep it up
from the wips so far this should be your best chop and as jack said pro worthy

AWESOME update. the rims looks epic man, really really nice work. add a few sunspots on the rims where the light would hit them. make them small and bright keep it up. follow svens advice too with smoothness. the smudge tool is your best friend.
