Nothing personal WAV, but that is a perfect example of why a cheap Mic, a poor soundcard and a free DAW is just what you don't need.
The sound is very poor- nothing like a professional recording.
There are breaths and pops, odd audio clicks and the overall sound is very boxy and lacking any top end sparkle.
(Auditioned on DT100 professional headphones.)
There is no way you should ever purport to record music for other people with a finished result like that.
It is possible that you cannot hear the faults- it does take experience, but they are there, I promise you. A student would fail even an introductory Music Tech course with a recording of this quality.
I will make no comment about the pitch, but Simon Cowell would.
