Very cool shot!! I like the "motion" of it. This picture has a lot of energy to it. This is one time that the lens flare really added to the picture, I believe, both by adding interest and an almost "mystical" feel to it. I really like the background you have used. By not being solid black, it almost looks to me as if the bike is flying through space or something.
The light on the cogs is a bit bright, and this makes it look ever so slightly out of focus. Also, I think it wouldn't feel quite so like it was flying out of the frame if it was a little lower and to the left more. Of course, if you want that "flying out of the frame" feeling, then pat yourself on the back, because you obviously succeeded!!
A great shot, and best to you in future challenges.
Wow, very cool image. I like the way the object is shiny, this adds a sense of texture to the image. I also like the reflection that is cast by the gold of the object. This makes the image have a lot of interest.
