A detailed pencil sketch of two swallows in flight, one flying directly at the viewer with its wings outstretched and body sideways against a white background, fine lines capturing their elegant posture and intricate feathers, a monochrome drawing that conveys motion and freedom, no shadows or shading on the page for a transparent background. The sketch is done in the style of a minimalist artist. --ar 21:32 --iw 3 --v 6
