For BMS, I know it’s a more serious topic, but it felt slow. Some advice I’ve received is to smile when reading (it makes a difference) and mark where you plan to take a breath. There were some unneeded pauses (between “bodies” and “and” in the first sentence, for example). Planning your breaths will help with that.
Motorcycle had a better pace – it sounded like you were enjoying the topic. One word that was a little rushed was “experience.” Take your time on long words.
One thing that did stick our for me was your final “s” sounds. The “s” is held a little long (“made from fresh ingredients” “expert chefs”) for example.
But, the tone is great. I don’t even have a dog, and I’m thinking about ordering some of this food!
I liked the very different tones for the two pieces.
For GrammarlyGo, be careful with the product name. You might want to slow it down to make sure it’s understood (they’d be the ones paying for the spot…). And, I did hear some mouth noise (clicking). I’ve been told hydration will help with that.
I loved the pacing for the Niagara Falls piece. But, be careful with pitch. It felt a little roller coaster-y. Pitch went up and down and up and down. I tend to do this sometimes, too.
