Unexpected Guests. A robbery Scene (Feedback please)

As the two robbers came in "Unexpected" outfits, they thought they had this robbery in the bag. One thing the two did not expect was the police coming from behind. (absailing down the window). This is a scene which I thought would be a fun one to do. The background in the windows is the grand emporium. I messed around with lighting levels a bit in photoshop.

 

Feedback appreciated :D.
