I love using this technique! I took one of my current home (Pittsburgh) a while back and it was pretty well received.
If you do this again (and you should!), I recommend getting an app for your phone like Blue Hour that calculates sunset and blue hour timing, travel path of the sun, etc. Start about 30 minutes before sunset begins and stop about 30 minutes after the blue hour is over for maximum color.
