I like the angle (height wise) you took the photo from. I also like how you captured the reflection in the side of the car. However, somehow I find the background on the left half of the picture a little distracting. Perhaps, the the white wall would make for a better backdrop to showcase the car more. This might be tough to do though if this isn't your car/you don't know the owner. Something to think about I guess?
I'm kind of unfamiliar with some muscle cars, is this the Barracuda with the hemi in it?
"To photograph is to hold one's breath, when all faculties converge to capture fleeting reality. It's at that precise moment that mastering an image becomes a great physical and intellectual joy."
