i know, all the fireworks shots were posted long ago, im a little late.
anyway - i took a different approach then others here, i went for the more abstract head on shots - with a full second exposure and letting camera shake and the motion blur do its magic. i used the 18-70 and the 70-210, sometimes zooming in during the exposure to get that look.
Let me know what you think. I think theyre kind of on the borderline of being too abstract.
