Only make the specific changes described below. The central symbol consists of a metallic silver letter O, an open parchment book and a large realistic 3D quill. O: Make the O smaller and PERFECTLY ROUND, like a true circle — NOT oval and NOT vertically elongated. The O must remain OPEN at the bottom exactly like the reference. The two ends of the O must NOT touch or connect. The lower-left end of the O must create a clearly visible, elegant, sweeping curve that extends downward and connects directly to the quill shaft. The right end of the O remains separate and begins slightly higher. The characteristic open-O construction and the sweeping connection to the quill are essential and must NOT be redesigned. QUILL: Keep the broad, substantial and realistic 3D feather style from the reference. The feather is muted light sage green / lindgrün.
