The first time I saw the Sydney Opera House (which was when I was 6 or something) I seriously thought it was an enormous tent. I thought it was cool and asked my dad if I could go and he was all like 'NO WHY DO YOU WANT TO GO THERE?! D<'
I'm 18 now and my impression now as someone who is looking forward to studying architecture in uni is that the Sydney Opera House is a prime example when preconceptions of a building are not used. It takes the idea of using unusual shapes, never going with the thought 'I saw so and so do this, I like it and want to do it myself'. It's an original idea what doesn't care what other people think. I think it is a prime example of Australian architecture (which I think is awesome sauce, certainly better than Singapore and Britain) as it really kicked started the the idea of slapping weird-ass-but-tasteful everywhere (which is a contrast to Britain's 'weird-ass-but-just-plain-weird-ass-and-ugly').
Also, since you're doing a graphic novel, I'd like to lend some help. For one (we had to do 12 minimum) of my final projects for Art (at high school level) was a graphic novel (which was extremely metaphorical and conceptual). If you need someone to proofread the storyboard or suggest ideas, pop me an rmail ;D
