Here's some of the stuff I've done come to pass a bit...
From last Halloween. Myself in my Spartan armour, a friend in my Ezio costume.
The costume actually looked pretty decent on him, since he is an actual guy and all, compared to me as a girl in it.
Since me and my friend were always the starting beaters on our team, someone made this funny comment so we made it into a motivational poster. A bit fitting. Plus I like this picture.
Also my team in the jerseys I designed at Quidditch World Cup V in November, in New York. We placed 7th of the 97 teams there.
