New Year's Eve Fireworks in Vienna

First of all I have to say that I am a newcomer in the world of photography although I have been interested on it for a really long time.
Having said that, I have to admit that the picture got my eye completely. I love how you captured in the same moment both the ignition of the firework, its trajectory and all the other fireworks all around the city. In addition, the foreground of the ice skating court (or whatever that is) provides a really interesting contrast with the dark silhouettes of the city's buildings.
On the other hand, the only thing that prevents me from adoring this picture is the slightly grainy look it has. I know that it is really hard to get clean images at night. However, maybe some careful work with a retouching program may be able to get rid of this noise (if you have already tried to remove this noise then just forget about this sentence).
All in all I really like the picture, and I would like to greet you for your choice of the moment. Congratulations.
