The colours really work well together. The depth of field is quite dramatic. I think the central positioning was a good choice. I also think the title is quite effective.
I saw the text before the photo and had a brief moment where I thought, "Not more fireworks!" But the photo of a flower surprised me. That may be pushing my rating for the photo higher - I'm not sure. But it is a beautiful photo, nonetheless. I would give it a 7.
It could be a bit more dynamic in tonal range. Although I understand why you titled it this way, because of the rather bland color range, this photo doesn't really suggest fireworks to me. Good subject and the centering works well.
Excellent DOF and nice sharp focus. My mind said "oh no.." when I first read the title before the image loaded but was pleasantly surprised to find this. Beautiful shot! Background appears a tad grainy which could have resulted from sharpening.
