Thanks!
The process was pretty much exactly how you described. Here is a quick snapshot of what my window looks like. Just so everybody knows, I put a lot more effort into blacking out the window than I should have. I was too 'lazy' to completely move my desk out of the way, which would have allowed me to put some curtains over the window, and I instead slid some cardboard and went tape crazy.
It was one of those "I put too much effort into doing it one way because I was too lazy to do it the proper way" moments.
I am also more fond of the last picture and I will definitely be submitting that one.
