Which of these pictures is more abstract?
Neither of these are abstract, but the second one is definitely moreso than the first.

The first has clearly defined objects and flow; it simply looks like a stylized art piece.  The second one, though it has clearly defined objects, lacks flow and is more open to interpretation.  It has some abstract elements, but overall, it is not.

Keep in mind that the term "abstract" is used to define art that does not resemble any other visual references in the world.  It is a bunch of baloney that leaves the viewer to be the one to interpret it.
