Dont know about making it sharper, I can read the 351-GT easily enough, perhaps some degrading has occurred when making the image smaller to post?
I don't mind the angle. I think with a static car, you need to introduce something to it. Having it dead even would be boring, and I think I would say as much also. I think the angle is *maybe* to extreme, but it needs an angle there for sure. I dont think it has anything to do with being different, perhaps artsy, but only in so far as recognising that the images needs something.
I agree about getting rid of the legs in the background though. I guess you stumbled across the car, so you had to shoot it in situ, which means putting up with the backgrounds etc. You could have tried for a shallow DOF, but then the ass end, or far side of the vehicle would be OOF also. If you were comfortable with
PS, you could vignette the image to remove the detail from the background.
If you find cars like this in future with crap backgrounds etc, rather than trying to get a whole car portrait, maybe try getting a series of detail shots, car lovers would know they came from a 351-GT without seeing the whole vehicle.
