Nice experimentation. I agree with you about cars looking interesting on long shutters, it gives a sensation of surrealness (i think thats the word im looking for) and this pic seems to hae that.
Lights at night....blurred that way.. some of my favorite things to look at. I expeiement a little (nothing here as I just joined) and love what happens. This is a great piece.
i love long exposures, especially in the city. and its also nice to see, youve managed to get the stars in there among all that glare and streetlight.
well done.
