Great stuff as always. I like the use of different textured fabric/paper to base your art; it gives it that slight edge, as can be seen on the first pic.
The second piece evokes some Princess Mononoke/Tekkonkinkreet feels; the former with the character design and the latter with the art style, though with some distinction.
I guess as people, we always choose to over-complicate things, which is evident among people that examine art pieces. Most artists, like you said probably just drew two lines crossing each other, no thinking too much about it, and now suddenly people are adding meaning to it.
