Both embankments - Moskvoretskaya naberezhnaya on the left, Raushskaya naberezhnaya on the right - and the greatest amount of ice of the River Moscow are displayed in this (see the birds on the ice of the river, the best description of them out of the three). The first focused on Kotelnicheskaya Tower, one of the Seven Sisters, the second, a merged image showed whole of the Bolshoi Ustyinskiy Bridge besides the building. (Read more info on Kotelnicheskaya Tower and Seven Sisters here, if interested.) On the very left you can see the green tower of Orphanage.
One of my most complicated merge so far, the left quarter of the picture was a frame with different focus & proportions & rotation, I had to play with the two frames a lot before completing.
