You chose a bit of a tough song to start out with! If you really want to improve, it will take much effort and commitment. Think about the amount of training athletes at all different levels of their sport need to do and its the same with how far you want to go with singing.
I think you have something good to work with, your tone will change as your voice grows so at the moment it just sounds untrained. Have a look at @Klaus_T page to find a list of Kens videos to start a daily workout.
When you sing, try and think about singing to someone or to an audience to get a bit more projection in your voice and start to listen for your pitch.
Work on the exercises that I mentioned, doing these will help develop your voice correctly, and using proper techniques will change your tone to be brighter and more full and more like a "singing voice". For majority of singing, you want to have resonance, so your voice sounds like you are an instrument instead of just speaking lyrics in pitch.

Keep it up!
Also, how will my tone change?
