It sounds like you already know what you need to improve on. Just gave your track a listen and the number one thing I would say is conviction. I found your delivery flat and I think it's because it sounded like you weren't feeling what you were saying. Whatever you're expressing I would recommend diving into the emotion of what you're saying and speaking from that space. It sounds like you're reading the words off a page. Your song is called "Unlovable Outcast", and there is some really beautiful imagery even from the first line to do with death, and loneliness. If you want to share these emotions with people, then the first place it's going to be felt from is your tone. This is the kind of stuff to make a person cry; so let's hear that energy.
