Putting the posters into context... the london underground... photoshopped photographs

This is how I am putting my posters into context. As I could not get them printed and actually into the stations. This was the best I could do.
I have put them in a combination of 4 sheets, 6 sheets and lift, escalator and stair panels. These were the ones previously decided on in the context part of this blog.
Escalator panels

 4 Sheets

 6 Sheets.

I feel these really put them into context, I could really imagine them actually being there. And the variation of posters rather than one single print makes people think.
I found this very challenging... my photoshop skills leave something to be desired, but I don't think these are too bad.
I have tried using a backlit effect for the 6 Sheets.
