Istanbul Tiltshift

The photo was taken on a really good day to do the scale model effect, because it doesn't have too much contrast on light and shadow. But the back part, and the front (which is blurred) should have been a little bit less blurred. Also, it should have been a little more gradual, like a gradient.
The colors are really vivid, which makes the picture resemble even more a model. The quality is also really good, so it looks like it has been taken from really close.
Although, the luminosity should be a little bigger, the city seems too dark.
A warming filter would go on well with the picture, to give it a brighter, happier, mood, even though the blueish tone, which makes it a bit gloomy, also makes it a really good picture (I don't know what's your intention to the picture, to give it a happy mood, sad mood, etc...).
The picture and the idea of it are really good, even with some little flaws.
