This album cover project explores a concept called "Moment of Tangency",
which is a term created by John Koenig for the Dictionary of Obscure Sorrows:
"If two lines are truly parallel,
it means they’ll never actually meet."
"If two lines are truly parallel,
it means they’ll never actually meet."
The composition was made on purpose using tangent¹ lines, which is something that should be avoided when drawing, because it creates unnecessary focus, but in this case, it adds to the concept, since it shows that they have a lot of things in common, and they share these interests by touching through these tangent lines.
They have everything that would make this a beautiful love story but time and place. They never saw each other (they are looking to somewhere else), and this is also represented by the only lines that are not touching: two parallel lines on the background, between their heads.
It's basically showing how many things in life could have been
different if only they shared the same time and place.
¹In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. (Wikipedia)
