David,

Is the melody 100% Suno?
It's very natural and lively.
The lyrics have been almost completely replaced, so I think it's 100% your work.
The Synth V and the choice of instruments are so good, and making it a great song.
If I had the opportunity, I would like to try using AI, but I'd be a little scared if I came across a melody that I thought was too good.
Enjoyed my listen a lot.

Best regards.
