The angled shot should be used sparingly and purposefully. The angled profile (like the first two you posted) generally look arbitrary, contrived and amateurish. You can't just turn the camera and hope for the best. The rear 3/4 angled shot you posted in #21 is somewhat more justified as you set up a perspective at the top left of the image. It distracts from the mundane setting. Let the composition of the image as a whole determine the best angle for the shot.
When I mentioned it before I was imagining it to look like the renditions of the concept STI hatchback... dosen't look to be wide enough though...
you made my day with those pics... thanks!
