That is an odd angle, or lack their of, are you sure this wasn't there before or caused by another incident or event? That type of scratch doesn't really look like a "hey f*** you', it almost looks like damage from an ice scrapper, poor carwash method, just not somebody walking by keying your car. Looks like a north south motion, not a traditional east west movement...
Not to get too CSI with it, but wen people key cars, they usually do it in areas that you will see, or to get back you, certainly it could be a lot worse - if it was a 'key'ing' event, it certainly looks half assed.
Good luck with the repair, fortunately, a good hood repainting is always a bonus!
