What is wrong with this picture?
What is it supposed to be?
For one thing, the highlighted bright spots aren't good I think. And it is too blurry. What are you trying to show??
@Ammaar Ghani I get your concept of a tire or wheel as in "the wheels keep on turning" and I like the mood and color combination but it's too out of focus overall. There should be one major area that is in sharp focus which here should be the wheel itself. I would also remove the spike-looking object on the right since it doesn't add anything and would give the image more negative space.
Unfortunately, glare from highly reflective surfaces doesn't do much for your image.
