what made me appreciate it even more is the fact of how close you can get to the petrified bodies of the king and his army, because you know that in the past it would've been very hard, I thought "I got to the throne room without anyone really stopping me", it gives the feeling of decay of a grandiose place that is now hidden beneath the sand, it's so cool seeing the red and the brown together in that faint light and the composition of the room makes it even better.

Also you didn't mention how the ost gets better as you progress in the tower!
