I actually quite like the cover for Broken Aegis. The first two covers were a little more character-based but I went for a (hopefully) minimalistic and simpler feel for the last two covers. The only concept that I had with this was surrealism so I thought of merging objects together. Okay, I'm just somewhat unsatisfied with how Heart's Oblivion turned out.

Now that I'm typing this, maybe this could make a fantasy or sci-fi series where cities exist in layers and each layer is akin to a different realm/dimension. And I guess a problem occurred in one of those layers, causing the overall foundation to begin to shift and the structure is threatened, resulting in a series of events our MC gets caught in.
