Yeah it probably was. I didn't see that haha.
I said before, but this was only to test how to actually edit the sky in an image. I hadn't really used layer masks before so I just wanted to see how it works and how to do it. I never planned on making it perfect. All I did was change the sky and added a reflection on the building.
If I was trying to do photo manip for real, I would have spent longer than 5 minutes on it XD
