Andres, I think the car looks amazing-really beautiful, but something about the reflection bothers me. Maybe try toning it down so it doesn't compete with the car, or even try a shadow instead. Like I said, the car part is great. Jon.
Actually, the reflection is completely wrong. Where's the reflection of the undercarriage of the car? Where's the shadow under the car.... it looks like you took a side view of the car and pasted it down next to it, but that's not consistent with how it should be. That's why it seems off; the angle is wrong, critical elements are missing, and there's no shadow.
Hate to be harsh, but it's back to the drawing board on this one.
