two-person bust 3d model

Create a highly detailed 3D bust of two real people based strictly on the provided reference photos. The result should accurately preserve facial proportions, likeness, and unique features of both individuals. The two people should be positioned facing each other closely, as if they are about to kiss, with a small natural distance between their lips. Style: realistic sculptural bust, suitable for 3D printing. The model must be watertight, solid, and printable, with clean geometry and no holes. Output as a single combined 3D object suitable for export to STL format.
