Fireworks are nice but having seen so many of them I really need something else in the frame to make it work for me, foreground or backround... Same applies to lighting photos and aurora boralis for example, just those alone do nothing for me unless captured very unusually. 5
Good abstract material but too much black area, I think it would be better to crop 1/3rd off from the top and a little from the sides so the sparkles would have filled out the frame. 4 from me, good luck.
