Hmm, perhaps I didn’t choose the best song as an example - I generally don’t sound great on upbeat genres of songs due to my dark and airy tone, but I hope some of this helps!
Basically, don’t be afraid to “break” consistency in your voice and get a bit gritty and dynamic. Think about what a vocalist might sound like, or even feel like, when they sing a melancholy piece, or an intense piece. Try studying and imitating some of the interesting elements of those voices, too. You might discover some fascinating results when you experiment.

Singing with more emotion is an interesting topic. When I first made my debut as an UTAU, my voice actually wasn't very expressive. In fact, quite the opposite - my voice was on the restrained side.. It sounded like I didn't really want to sing...
So to improve, I actually looked towards human singers to develop a more expressive sound, because I wanted to sound as good as them!
Most UTAU will have a pretty consistent, and clean sound to them, they will sing songs and sound stable throughout them because they will sing that in one way.

But a more expressive sound requires that extra ‘oomph’ in both the consonants and the vowels... a bit more air, a bit more crispness and strength in the consonants, a bit more vocal fry.
