Heres some comments, they may seem harsh but don't take them that way. just my feelings.
I have 2 major criticisms
1) The borders are terribly distracting and detract from the photos rather than adding.
2) The watermark is horrible even more distracting.
Trying to ignore the above I have some minor comments:
Photo 1) car seems a little soft, the high-keying has removed details form the car which would be nice to see in the highlights. Compositionally, I don't like the wasted space at the bottom and would prefer a more in-the-face front of the car. Lens flare is also distracting.
photo 2)highlights are better, prefer the composition, and seems a little sharper but not perfect. The radial blur looks very fake. I think the idea of the effect is very cool, but it just isn't working well here. Perhaps a more subtle of even a softened effect would work better.
Photo 3) The out of focus part is the closest and largest part of the image, the in-focus detail is the re-counter and fuel gage. I have no idea why. Why not have the speedo nice and focussed. Its not like the rev counter is showing anything interesting, and who cares about the fuel?.
