Mercedes Benz S-Class 2014

This is Mercedes Benz S-Class 2014 (Exterior Only) modeled and rendered in Blender 3D. I tried to render the model with real environments and HDRIs because my goal is to make the model as photo-realistic as I can. The interior part is not modeled which is why only the Exterior parts are rendered.
Some of the renders are shown below.

I am selling this model for just $1 at my Artstation Store. Kindly keep in mind that this package only contains the exterior part of the vehicle and not the interior. The backgrounds shown in the images are also not included as I do not own them.

Any critique on the model is much appreciated.

Thank you for choosing this product.
