I love the background, but the street lights kind of blend in with the sky and there should probably be clouds, but it looks kind of, still.  Some of the details on the car are nice though

I like it Jedi, Only I agree with onek, also too much blank space

i dont see that motion burreness at all.....aeverything seems a bit jaggy an i think u should have lost that outline  also the aa on that diagonal line on the car doesnt work
