Why did you think there'd be a problem with the guitar solo? Unless you're actually doing a dedicated A Capella style song, there's no point just uploading your singing - we want to be able to match you to chords, and music helps to support your vocals. That's the point of music. Maybe you should've sought out an instrumental version.
On top of that, there was that section at the start where you must've gotten close to the microphone, and as such, you distorted your voice out. Next time, ensure you stay the same distance from the microphone.
Finally, you're singing with a very nasal tone. A lot of sounds which should be 'ung' turn out to 'uhn'. It makes this song very difficult to listen to and, with the lack of power behind your voice, is also causing you to flatten your notes. So, 1/5 and 2/10, for trying, but you need serious work.
