This is a really good start with Synth V. You can tell that you're used to working with (your own) voices, which is very helpful with synthetic voices (same here BTW).

I agree, Sade would be a great fit. Transpose the song down a third or fifth and Natalie (who's not as good as Solaria up there) on main vocals would probably fit Sade even more, her voice has more character.

But let's not forget that it's a good song with good lyrics, and it's well mixed and produced.

I like it. And that's what counts in the end.
