Hayley, who is the office's resident cosplay expert, said it best: "You get amazing costumes that would have won national competitions in Australia that don't even place at Blizzcon."
The level of passion at Blizzcon is insane -- and the costumes, even more so.
The YouTube channel Sneaky Zebra has a penchant for doing cosplay music videos from major conventions, and Blizzcon was another perfect opportunity given the level of passion and quality of cosplays on show.
The growth and accessibility of 3D printing in particular has led to some sensational designs, many of which you can see in this video.
Truly astonishing. I wish I had the artistic eye and ability to make anything even remotely this good. Hell, I'd be happy if I could just do the face paint and makeup properly.
