The door lines are toony and some of the places are in low res too. The rear bumper is flat, other than that, it is good.

good chop

Thanks, which parts are low res??? I try to do this work more realistic... and want to see mistakes

I think the bottom of the bumper is flat mostly close to that vent.The shading by the side skirt also looks a little messy.If you take a look at the car overall you will see that most of the car is shiny but then the bumper looks matte.Hope you understand what i mean.
Otherwise its not too bad.

If the tyres were a bit darker and undercar shadow not so blurred, it would be great.
Overall nice chop

Thanks, as I right understand I must add more lights\shadows on body, add another shadow under car
I really want to do this car more ideal)))
Something more??

Update with new lights, hope it better now)
