A good idea, but would have been better executed if you could have found stationary traffic beside light trails. Another more minor point is that you're missing a space between 'Life' and 'In'.
Great motion feeling in this shot. Love the star effect on the lamps and how clean it is for an envening shot. Nice trails. The type face is nice for this particular poster, but the colour of the text clashes with all the red in the image. White or grey would have stand up better. Well done otherwise.
