I find the leaves in the foreground too distracting - I guess the idea was the frame the landscape, but I find them too much. it looked like a nice sky though that could have been empahsised more. an interesting skyline nonetheless :)
I somewhat like the foreground. And I know that all the books say you have to have a foreground, but what the books don't say is the foreground should compliment the picture either by framing in a pleasing way or thru repetition of the shape of the body of the picture. The foreground should not be more overpowering than the body of the picture. So using this, the red in the leaves compliment the red in the one building. That is good. The limbs on the side just get in the way and distract from the view.
Nice foreground for the city - it adds a lot of color to an otherwise near monochrome cityscape. The red light at the top of the building near the center picks up the bright red and draws me into the photo.
