Camera appears off-center or rotated slightly

Hey all, I’m hoping someone can help me understand what/why is going on.

Both the Top Platform and the Bottom Platform are the same width and height, and they are the same distance from the center point of the screen. Yet the Top Platform appears more narrow and has a larger gap between the edge of the screen.

Can anyone tell me what’s going on here?

“Oh… oh… oh… pick me teacher! Pick me!!” waving hand eagerly

“Yes?”

“The Z scale on the two cubes is not the same?”

Happy Friday the Thirteenth!!
