Pitch needs to be much lower as your current voice doesn't match the character's age or cold demeanor. Delivery is well enough paced, and the emotional peaks are done well enough but I the pitch seriously hurts how convincing they sound. Tone needs to be much more dark and merciless, as it seems you have the idea for this but lack the intensity to give it all the more impact. The pitch remains as the biggest issue with this audition as it doesn't fit the character and lowers the credibility of other aspects of your audition. Lower it and increase your intensity if you wish to try it again.
