I think, really, those commenters are correct - and certainly it has afected your score, that the image did require an explanation in order to fit this challenge. Personally, I don't find these recreation of period challenges fun - especially given the very demanding public voting; can you imagine entering an image processed to look like an 80's colour photograph? I don't think that would score too well either. So really, I think we were only left with recreations of fashion and certain american crazes of the time as an option.
The other problem is that this is really a pretty ordinary image: the technicalities are all there, but the point is more about the point of view and the framing that you've chosen. It's a very everyday approach to a stadium shot, even though you've been quite careful to place the rings strongly in frame. The trees abscuring large parts of the image are a problem I think, complicating and disrupting the very clean lines of the building. I would have tried to make more use of the curves of the concrete against the curves of the olympic rings - there might be interesting tonal and textural differnces there - always presuming you could actually get that close to the stadium, of course.
Nice image, maybe removing the light at the bottom of the image would help focus attection to the important parts of the image. Nice shapes and lines though.
I remember that! The title is going to hurt you in the end though I think, just a simple, Seoul Olympic Stadium would have been fine. That alone evokes a ton of memories for me.
The shot is okay, nothing really jumps out at me and says, LOOK AT ME! and holds my attention. Seems a bit too dark and slightly, ever so slightly blurred. A 6
