It's pretty realistical, but the hood vents and the side are ugly IMO.
Just don't match the style on an Alfa.
The FB looks good, but it's a bit off in the down corner naer the front wheel. The rear wheel is a bit off too and needs some shodow.
And another big mistake, is that you have sky reflexions on the roof, but the car is in another background. The selections can be better.
Something i love, is the Alfa in the back

. Just perfect!
