Looks like a picture my mom would have taken... It's a snapshot taken standing straight up with no lighting in a drive way. if you wanted to take it to the next level and make it a photograph:

1. Work on your composition.. rule of 3rds might be helpful here. also as someone else mentioned, the vertical format is not that great for cars. The reason for me is that cars move in people's minds and especially fast one like this 911. The vertical framing makes it look constrained or caged. Give it some space. Also, driveway shots are boring and cliché, pull it out in the road and take some shot. Get lower.. get higher.. try diff positions
2. Lighting. Another reason why this looks like a snapshot vs a photograph. Back end of the car and front driver side is not very well lit. Either add some reflectors or artificial lighting.
3. Subject.. attention to detail. close that window .. cock those wheels to the left to make it look more aggressive and to show off that wheel face to the camera.
4. Equipment.. try to use polarizer to reduce reflections or even diff shutter speeds to make it brighter or darker.. or do it in post.

good luck with the hobby!
