Nice looking chop, or facelift might be a better word! Hehe. Had to examine the original with the chop a few times to see what you did to it. Overall I think you have done a good job, also in capturing the GTI essence, not just through the obvious grill, but with the stance of the car and other mods. Really nice clean style
There are however some misstakes. First off the rims. You havn't changed the color that much on either the car nor the bg, but you have made the new Bugatti rims all cyanish. They should be more like the color of the original, a bit yellowish sort of

Then there is the shaving of the trim on the door. It's pretty well done, but if you look very closely you can still see a ghostline there from where it used to be. You wouldn't see it if you didn't have the original to compare with, but now we do so. Hehe. My advice to fix that is to take a brush with pritty low opacity and just go over that area a few times to really blend it with the rest of the door. Simple fix i'd say

The bzela text on the numberplate is a bit off in perspective also. I think it should be pinched on the cars left side so it becomes a little thinner on that side, but just very very little. Lastly the new seats stick out a bit much. You should try to colorcode them a bit more with the rest of the interior, which means making them a bit more purple. Maybe also add some noise to give them the same texture as everything else.
Overall it's a nice clean cool chop. If I hadn't had the original for comparison i'd probably not found that many errors, or even seen it was a chop to begin with. Hehe. Great job, and keep it up

My main advice for you is to go back and look on the original car a bit more. Check things like original car rim color, color of the interior and things like that
Cheers!
