It's really hard to figure this out. The steps look pasted over the top of a 2D image as there is no depth either on the pyramid itself or to the steps that would be carved into them. Realistically, from the POV, the steps should appear to be spaced closer together the lower down(further away from the center) they go the sides.
This lack of perspective is made even worse by the quite heavy shadows on some of the objects at the top while there is no(or no consistent) light source on the actual pyramid itself. My suggestion here is to start with the base of the pyramid and get it and the steps in place and looking good(Just use a solid color temporarily and you can add the snow effect later on). Then start adding in the other objects.
