Lower it to allow bigger changes, or raise it to preserve original details. - Modify the **Text CFG weight** to influence how closely the edit follows text instructions. Increase it to adhere more to the text, or decrease it for subtler changes. - Experiment with different **random seeds** and **CFG values** for varied outcomes. - **Rephrase your instructions** for potentially better results. - **Increase the number of steps** for enhanced edits. - For better facial details, especially if they're small, **crop the image** to enlarge the face's presence.
