A nice experiment, Julie. The little shapes are interesting. I think the wide aspect ratio hurt your score, though - it doesn't have as much impact when it fills so little of the screen. I love how your commenters did guess at what it was - isn't it fun when they engage like that? :)
It does look really cool! That is some very nice detail you have. Feels industrial. I'm guessing the low votes were due to the pano format. I guess. I haven't the foggiest why this would score below a 5.
