At 4.4L and 333 hp, it definitely sygnifies power; However, the picture is horribly composed. Too dark, glare, asymetric, distraction from the white coat in the back, etc.. I'm sure you could have done better...
a much tighter composure on the front end of the car , perhaps a foot or so higher and a lighter exposure would have highlighted the more interesting aspects of this automobile, the Z-lights, kidney grill, roundal, euro style plate and more detail on the chin spoiler would have done more justice to this 'BMW'.
the shape of the car is far too indistinct - it would seem that lighting was totally insufficient... it might have been improved once you got home; a slight increase in brightness and a huge increase in contract would have improved it. Also too much of the car has been cropped out, the person at the back is distracting... Though i am personally unable to equate a BMW with strength (horsepower, yes) I'm sure you might have found a better example out in the street under natural light.
