Lets talk about shape
Shape is one of the seven elements of art. We can think of a shape as a line that found closure.
There are infinite shapes in the universe but we can break them down into two categories. Organic or Geometric.
Geometric shapes rely on mathematics. Consider the shapes we studied in geometry class
like triangles, circles & squares. Every shape that doesn't rely on basic math is an organic shape.
like your face, that's an organic shape that gets more beautiful when you smile.
