Well, My first impression on looking at this was that the bursts were added in PS somehow because of how clear and well timed they seem to be. Technically I think this photo is very good, the image is sharp (for the conditions) and well exposed. As an aside, I like firework photography. Getting good images from firework displays can be difficult (vantage point, surrounding lighting, the inevitable "blast fog") but you've done a nice job here. CG
