Welcome.
This is a good song with a good backing and a nice melody well sung.
You do need to come to grips with editing your vocal though...there's mic handling or other room noise just prior to you singing as well as a bunch of essing & some plosives.
Jump onto Youtube - you'll find some Sonar Platinum specific vocal editing/de-essing etc tutorials there.
I don't expect any one, myself included, will get a great handle on dealing with sibilant sounds in a hurry but there are plug in/VSTs that can help you straight away as well as more manual yet more effective processes you may wish to consider learning.
WHY?
Simple answer - your song is worth it.

Cheers
