The pedestal, capital, and cornice of each column has skulls, that's eighteen, plus two more in the flames at the top.
I count/estimate twenty two circling the platform.
There are seven in an alcove on the side of the stairs, plus, assuming symmetry, five wraith figures under the platform. That's another nineteen (assuming another alcove on the other side).
It's hard to believe you wouldn't see another dozen skulls if you were looking up the staircase.
That's seventy three. Yup, a weak imitation of GW. Unless there are some we can't see.
But since it's an "enhanced" GW piece maybe the enhancement was puttying over some skulls. I've improved some figures by covering some things.
In all seriousness, it's a very exciting piece of terrain.
