Based on the description of the artwork—a depiction of a small raft filled with exhausted people clamoring for attention from a ship—it sounds like this piece is likely a two-dimensional representation created using paints or drawing materials.
If it is created using paint, it should go in the painting area. If it consists of some sort of ink or multiple layers that imply printmaking techniques, it could belong in the printmaking area. However, since it describes a scene that is likely visualized in paint, the most appropriate placement for this artwork would be in the painting area.
So, I would place it in the painting area.
