Fireworks shots

This was my first attempt taking fireworks shots.

Any comments welcome.

Nice timing.
They just seem a little soft, i see you shot 2 Seconds at f7.1 and 200ASA.
Perhaps a narrower apature would have given better depth and detail at a higher ISO value.
Saw a firework shot taken a while back in Australia which was a stunner, largely because it had silouette of the ground showing height and scale too.
Good first try though.
