I wish I saw this post earlier, I was there Saturday and had an awesome time. Did you end up going? If so did you see the models with the "We Are ODST" armor by the halo booth?
It would be very appreciated if you posted various shots of your armor (close ups, profiles, separate pieces). Its probably a hassle to get in and out of that thing but I know I looked for every excuse to get into armor when mine was all set up :p
Also, how long did it take you to get to this...
