Where in the QC is this? #4½ (Extra Difficult)

I didn't get any good "Where is this?" images this week, but I'm still going to try and get one either Friday or this weekend, and put up Where in the QC is this? #5 as soon as possible. However, since its Thursday and there's supposed to be one today, I'll give you folks this one to chew over. In my opinion, its much harder than last week's, even though it shows more detail. Bonus points if someone gets this one.No clues for this one; I'll give the answer hopefully tomorrow or Saturday when I put up the real #5.
