Okay well first of all I learned a lot from this build and will transfer that to when I eventually build another one. Report from the con on my costume was that it was a huge hit and I could barely walk 15 feet without being mobbed. I was very happy with my mobility as I was able to easily walk throughout the entire convention and even on the crowded floors but I was also very glad to stay in the hotel attached to the convention centre since it meant I barely had to carry anything. I encountered a few problems mainly with the legs and stilts.
First of all, the stilts. The right one broke within 20 minutes of wearing the costume. The problem was from the wood I used being too cheap and tearing apart under the stress. In an attempt to fix them I grabbed the only thing in the close by corner store that I could feasibly use...tins of cat food.
This worked for about an hour the next day then promptly broke as well. This was made worse by the fact that the tine then broke open and filled my boots with cat food...I count it a lesson learned.
Secondly the bolts around my knee joint had a habit of working their way loose and then rubbing into my knee. This caused a bit of bleeding but was something I could fix and love with. Here's what my knee looked like.
