Here is a version with the girl that you said you wanted. I think it is ok if you want to capture young clients, this is a smart move, not too cheesy, but cool. As I said, we need a better communication so I would suggest to do this over skype. You don't have to be limited by time, because you have 2 weeks to choose the winner after the contest upload time finishes, we can do miracles by then. Talk to you soon.
Also could you please mark what is lightbox 1 and lightbox 2 on your pictures because I can't see the dimensions on this clearly. I want to design this but the brief is not that clear. I'm waiting for your feedback to continue working on this.
