Very tilted. Also, the flash glare obscures the label on the can quite a bit. The color looks off. Skin looks purple and the gingerale does not look like any gingerale I've ever seen.
The horizon appears to hav fallen to the right in your part of the world... :-). The straight-on lighting is a bit harsh as well, which is more of a problem than the falling over.
This is a very creative photo! But there a few things that bother me... photo could be rotated a tad to make everything straight. The reflection on the can and glass is distracting, and the model's hand is blurred (perhaps due to slow shutter speed). I like the concept overall, though!
