I agree in especially the first one. It was quite a challenge from the original content as the bitrate is quite low still, and in that particular case it was quite severely compressed. I had to dig quite deep to get the headroom back.

The last one was my first attempt.

I think the middle one is okay considering. By the time I got to that I had figured out how to get Suno to create multiple takes with much more open mixes, which left me a lot more latitude in the studio.

I expect I will get better at it, and I don't doubt the compression artifacts and the rest will improve.

To me at least, it is quite impressive where we are at. A ways to go, but very promising.
