Not doing anything for me for a night shot as there is nothing holding my interest that stands out. Sorry. Maybe a little more practice on some other subject?
I want to like this, but without a pattern you don't really have a focal point and need something like a sparkler or source creating the sparks.
I like that this is different than the typical fireworks shots, and I personally love it!
Nice shot with the fire works and sky , voted next time try a shorter exposure on your shutter speed,still a cool shot,
