Note the significant change to the side window design, a more complex curved surface instead of a half-circle. Below those are alcoves with designs – there might be varied designs in the future instead of the same one four times. The buttresses on the sides are new as well, with a fancier curved design. The three-star at the top of the tower is now made of glass with backlighting. The circular window in the middle now has support beams running through it.
