From Black and White to Colourful Photo

I've took this photo in Zagreb, Dugave and it was just an ordinary photo - nothing special, black and white urban photography, but then I decided to use Photoshop and put some colours in it. After few hours (7-8; I worked whole night on this), I've got some cool, dreamy colours here. I really hope that you will like it and that you will be inspired to make your own experiment here.

You can see my original shot, too :)
