Your intimate approach to the read is engaging and adds a unique dimension to the delivery. However, it's crucial to ensure that the tone aligns with the character's essence and the narrative's intent, particularly when dealing with a character like Mrs. Nillimore.

If the narrative's focus is on the character of Mrs. Nillimore and the emotions associated with her, your delivery should reflect the specific emotions she evokes, rather than a general sultry tone aimed at the listener. Consider the nature of your character's relationship with Mrs. Nillimore. Was it affectionate, respectful, or nostalgic? Channeling these specific emotions will help convey a more accurate and poignant message that resonates with the true spirit of the script.

To adjust your delivery, think about the emotional impact Mrs. Nillimore had on your character. If she was a comforting presence, your tone might be warmer and more tender. If she inspired you, perhaps a tone of admiration and respect would be appropriate. Reflecting on these details can help you refine your delivery to ensure it not only captures the audience's attention but also faithfully represents the character's feelings and the script's deeper themes.

In summary, while your intimate delivery is compelling, aligning it more closely with the character's emotional landscape will enhance the authenticity and impact of your performance. This approach ensures that the essence of Mrs. Nillimore and her significance to the character are clearly communicated, making the read not only engaging but also deeply meaningful.
