|Greetings from the Critique Club!
WOW! You did better than I did with my fireworks attempts. I didn't enter because mine all sucked, but this is nice!
The clarity and sharpness of the shot is very well done and I like the colors very much.
Reading the comments I would have to agree that the negative space in this shot doesn't work that well for the shot. You aren't using the rule of thirds to draw my eye into a certain area, there are no real leading lines in or out of the shot and the overall composition due to either the crop or lack of crop leaves me wondering what to do with all that extra space. A tighter crop to possibly bring the fireworks more to the center might really help this shot. Also just a bump n the contrast or curves or levels to really make the colors pop might make more people stand up and say, "WOW!" insteadk, "Yeah, that's nice."
Hope my comments help, looking through your portfolio you have some wonderful shots, a real eye for some of this. Welcome to DPC and Good Luck In Future Challenges.
