Just for clarity, I made it not in the Photoshop but in the Foundry Nuke.
This is special soft for compositing tasks like this one.
It's more flexible than Photoshop. That provides an ability to make changes in any part of the work at any stage, and that's not always possible in Photoshop.
This is a short demoreel of this work, for visibility. http://www.youtube.com/watch?v=2BME7XdYcBg&feature=youtu.be
And I have a big experience of compositing work for movies and TV series and also for music video.

This experience lets me make this work fast and qualitatively.
