Played with the lighting setup.
Switched from ACES to TonyMcMapface (Bevy's default). While ACES is very common, it forces a very specific aesthetic and makes everything look burned. TonyMcMapface is "boring", but it's good because it provides more control over the aesthetic.
I also tweaked the lighting color, adjusted the environment map intensity, and disabled bloom.
Here is the before and after.
