Sounds a lot like Finger Eleven, so I'd say you're doing a good job! Your vocal tone can use a bit of work, but it'll come in time

Great song man. Nice melodies on guitar and vocals. Your voice is quite good considering you don't regard yourself as a singer. While there are things you could do to improve your vocal technique, you're voice has an artistic quality to it, which in many cases is more important as it makes your voice unique and interesting. That's what will grab people's attention.
As a suggestion, you could try varying the dynamics and intensity of the vocals parts particularly in the last chorus or you could add a bridge to make the song more climatic.
I noticed you do that with the backing vocals in the last chorus so maybe you could build the lead vocals up a bit more too.

Overall, I really like the song and look forward to hearing more from you.
