Nice job! You have a very nice and clear read here which is super great. As for the scenario, remember that we want to hear you project your voice out as if you’re in a gymnasium with no microphone and you want people to hear you from the other end of the room. Make sure you use your diaphragm and take a big, deep breath to full up your lungs and push out the words to give them power. 

You tend to stay within the same tone the whole time in your performance. Think about playing around with the intensity of emotions like maybe excitement. If we think of this as advertisements, you want to really grab your audience so changing up different moments with volume changes, emphasis on certain words, pacing, etc can really make this catch their attention vs staying in that neutral tone the whole time. Sometimes the audience can lose interest if it's the same the whole time.

It sounds like you run out of breath throughout the sentences due to not taking a big enough breath, so make sure you do your exercises and fill your lungs up so that you can power through more vs taking more pauses throughout. Can’t wait to see your progress!
