They are mundane. Usual. Common.
Even outside of simple appearances, most people are dull empty husks without interesting aspects about them whatsoever.
Interesting humans exist, but they are few, and at the end of the day, you're choosing an exceptional piece of the average, where a dragon's average would have been above even that.
The majority of humanity have so little of note going on for them, I have a hard time making note of their mere existence. A few small details might change, hairstyles will be different, heights come in different variations, but it's nowhere near enough to make me care.
Honestly, I just don't get how people manage to settle for so little.
