Rangers Fireworks

I photographed the Texas Rangers Baseball game tonight and much to my delight there were fireworks after the game. Woo Hoo! I love the firecrackers. I did not know ahead of time that there would be fireworks so I was unprepared but I did OK without a tripod. I balanced the camera on a trash can with my fist under the lens to keep it angled up a little. F/8 at 4 seconds. What do you think?

Apparently the Rangers have fireworks every Friday night so next time I will be prepared with my tripod and a fisheye lens to get the facade of the ballpark from side to side. Oh it's going to be so cool!
