Here are a couple of shots I took at New Year. They are not very good, but they are my first attempt. It was basically pot luck as there were fireworks going off in all directions.
Good job for your first attempt. My first attempt at shooting fireworks did not work at all. I do like the tree shape of the fireworks and how they fill a lot of the frame.
Just a suggestion: next time try decreasing your shutter speed so you capture more light from the fireworks. Also, try not to shoot with a tree right behind the fireworks; it's a little distracting (if you look closely).
Besides those suggestions (which are only my opinions), I think you did a great job.
