Partly yes, but that was due to perspective being relatively unknown until the renaissance and elaborated on by the great masters of the time. It's the key reason why so much of the aztec's art that exists as sculptures and slabs were more extreme with their designs.
It was easier to work the perspective. The issue with OP is that, he doesn't actually work through what made the drawings interesting. I'm talking about the color palette, and the more interesting designs that the culture is known for. Even the line quality is fucking garbage when you compare it to classic aztec art, the only difference is that even they made great use of of the 2d plane, since they didn't know much of the perspective planes in drawing.
If you look at some of OP's drawings, he's actually drawing in ways that fuck up the perspective royally and make parts he's trying to bring out flatter than they should be. That's not aztec, or "aesthetic" that's uneducated and lazy.
