It is certainly a "burst." I think the closer crop to fill the frame makes me like it more then most "firework" shots. Rule of thrids placment also enhances the image. Well done.
I don't really see the burst of color in this photo.... :P jk
I really like the lines and colors here as well as the way you've weighted the composition. Nice shot.
interesting fireworks--technically well done, but it seems to lack color, unless the exposure is too high and colors were over-saturated. I think the theme of "Burst of Light" would be more appropriate. Promising image.
