Good capture of city mood w/ scale and grey color for sense of sameness in city life. What tools did you use if I may ask?
Very good for a first try. I did notice the perspective lines on the street should come closer togeher as they get further away. Other than that it looks very nice.
Well, adding some perspective would improve it quite a bit.
There are plenty of online tutorials on perspective, or you can get the book by Norling on the topic.
