Ha fun playful delivery. Sure, not sounds fake, because it doesn't seem like you're talking TO anyone just having fun. A great rehearsal, and great practice for being expressive and trying out emphasis to see what feels right. It's like a character here, which gives you that fun space to play and try big things. But the YOU of the read will keep coming as it's strengthened with the work and practice. Would you respond to the delivery if it was live on the street? It's certainly entertaining and that has engagement value. Also the character is interesting so you're prob getting ppl intrigued by the unpredictability you're sharing. Feel free to breathe off the lines too, those spaces can always be edited out and no one needs to hear them when it goes to air, and then you can power up, deliver, repeat until you're satisfied. Stamina grows, but a breath pause is easier to clean out than breathy work. You've got a lot of creativity, The 5W's you imagine and how the listener might react so you can adapt and keep their engagement while convincing them will get stronger as you play and hone your commercial voice.
