It is a very nice picture, your rendering skills are great but this time I believe I can find 1-2 things to say...
1. The lights you use under the balcony look very big and very bright, make the smaller and weaker.
2. The light at the lower part of the picture should be less, according to the time your background sky shows. It looks like it is 19:00 on top and 14:00 at the bottom of the building...
3. I am not a very big fun of motion blur, it doesn't seem to fit in all cases... Your is one of them, I would prefer the red car stopped. Also that thing close to the tree that looks like human, it travels with 80Km/h!
I think motion blur fits for objects close to the camera, the red car is far away to show this effect.
FYI, my renderings are not even close to yours so don't think this is an expert speaking, I just have these comments. Anyway, it's a great picture.
