Very overprocessed and has some ghosting going on. Also, since the window doesn't seem relevant to the "story" I would've had them step a few feet away from it so that I could isolate my subjects from the background; as it is, I find the lettering on the window distracting.
Way over HDR'd, Topazed, or what ever program you used. This would have been a really nice photo with out the over processing! You have a great capture wonderful eye contact, Super Faces to work with!! I can tell you did put a lot of work and thought in this, I'm going to give you a 6 for the hard work you did! Just back it off some next time!
