I exhibited my first MOC at my first show in Sydney, Australia last month. Not being a member of a LUG made it a great experience, talking to all the members and getting the low-down on the scene and their creations. 25,000+ people came through the show in 9 days ... it was umbelievable talking to sooooo many people.
This is the MOC -> http://www.eurobricks.com/forum/index.php?showtopic=81707
Considering the numbers, there wasn't really any damage ... a few soliders moved a bit, but nothing to worry about ... (which I did at first).
I was overjoyed to win 2nd Prize for best in Show, actually beating the 3rd place Ryloth Refinery Battle that is featured on the frontpage of Eurobricks right now .... By the way, the Ryloth scene looks far more amazing in person, it's so good.
I am already excited to build something else and exhibit again ... feels almost like releasing a 2nd album for a band, can you make something better than the first? :-) LOL.
