I think there is nothing you should be worried about. I'm (almost) in the same situation as you (married on June and my wife is the first winner). Actually I'm not worried at all because our relationship/marriage is genuine (we are together from high school, plus we started the marriage process like on March - we had the celebration in Italy and there takes a little bit longer the hole process). And your relationship/marriage looks genuine as well. No worries if you don't have pics from the "celebration of marriage day"; britsimon can not know how horrible the place/office where all takes place is in Albania and usually nobody takes pics from that moment.
But britsimon is right saying "they don't mind that a couple get married to take advantage of the win as long as that couple were a real existing couple". A friend of mine passed through the same situation last year (dv 2013), getting married with her boyfriend with whom used to be together less then a year, and i was not a problem for the U.S embassy in Tirana - they are in Florida now
So again, no worries about the marriage problem.
If you would like to read abut a real interview experience of this year from U.S Embassy in Tirana, search "llotaria amerikane" at "peshkupauje", the guy there had CN around 8000: lucky him
Aah our cn is EU29***.
