The character sounds a bit scared, as if they’re afraid of what they had created. I would say either lean into that narrative or move more so for the advertiser read. it's important to decide whether the character is genuinely excited about the product they're promoting or if they have some reservations or fear about it. Once you make that choice, it can significantly impact the overall tone and energy of your read. If you choose to go with an enthusiastic advertiser approach, as often seen in commercials, it's vital to fully believe in the product and convey that belief through your performance. Enthusiasm can be contagious and help sell the product to the audience. On the other hand, if you decide to explore a narrative where the character is apprehensive or scared about what they've created, it's essential to fully embrace that emotion and convey it authentically. In this case, you might emphasize the character's uncertainty and perhaps incorporate elements of suspense or hesitation into your delivery. Regarding using a different voice, it's crucial to balance vocal creativity with comfort and sustainability. If a particular voice begins to strain or feels unnatural, it's perfectly acceptable to adjust it to a level that is comfortable while still serving the character and the script. Whether you opt for enthusiasm, apprehension, or any other emotion, commit to it wholeheartedly to create a compelling and engaging read. Keep up the great work in exploring different characterizations and emotions in your voice acting!
