Glass Towers In The Heights

I used to work as technician about a year ago. This job granted me an access on the high rooftops in our capital Tallinn. I did get to experience breathtaking views very often. There was a day when i was doing my job stuff on the rooftop again and next to me were 2 higher glass towers. All the buildings were very close to each other, included the one i was on top of.
I took a photo of these two higher towers because they looked so massive and awesome in this gray background. Unfortunately they dont look that massive when looking from photo. I actually stared those towers that long and i got a feeling that they started to fluctuate. It is safe to say that this is probably my imagination.
This picture is my entry for steemit photo challenge in #architecturalphotography.
