So we settled upon this design that fulfilled all the requirements. It was a very hot and windy day at Randwick racecourse early in December. We had to underinflate the balloons so they wouldn't burst in the heat, and we had to secure the frames of the almost 3mtr tall 80 sculpture so it wouldn't be blown over.
...Alicia would love to be able to give up balloons to be Australia's Next Top Model. Please no-one tell her I posted this pic.
