Very creative composition (and title). The image in the mirror is slightly overexposed and not well resolved, and it would be nice if the foreground grapes were in focus. But I do think you succeeded in communicating the idea you intended.
this is one of the better car mirror photos i've seen. normally they look boring but this one is actually used to good effect, to pull the viewer into the mirror by using nice leading lines to the house. 8
Wow, here's a neat way of organizing an otherwise busy landscape: frame the neatly planted trees (nicely done here), and show the bonus stuff as well (nice fruits!)
I really like the idea and the photo. I think the mirror looks a little tilted, (for the drivers use I'm sure), but still think it would look better straight. 9
I think this would have been the winner of the contest if you eliminated the mirror and took a straigt shot of the winery. Look at all those grapes!!!!
