One other thing i note in Zelda's pyramid that is worth keeping is how the "vertical" lines of the side bricks are parallel to the rear edges of the pyramid.

This helps the player believing that the structure is "normal" despite skewed perspective etc. on the rightmost pyramid of what indigo called "helmsperspective", you have those line forming a nearly 90° angle, which completely ruins the perception of the volume. Whatever you pixel on the rear side of that pyramid, it's gonna to look awkward (imvho).

the leftmost pyramid on this third picture follow the "bricks // rear edge" and it has a strong effect in making me believe in the volume. Yet i still belive that it won't give you the feeling that you see a square-based pyramid unless "front edges" are sharper than 45°
I also disagree that Zelda art is better than anything posted here
Have we all forgotten that "megaman mockup frenzy" ?
