well I hope you dont mind but I will elaborate a little more on everything..not just reverb. All just my own opinions though.
First, the reverb on the backing vocal that comes in " I'll be thereeee" is a little much. try to tone it down so that it doesnt come in so aggressively.
Overall the song has a good rhythm and vibe to it. Two things I think it is lacking. first. the guitars and overall recording need to be cleaned up. It sounds slightly out of tune on the guitars. . and a little too much treble on it. Try different micing set up or perhaps some EQ. What kind of guitar is that and what type of strings are on it?
Second, from a songwriters perspective, I think that it needs to have more of a chorus. The part you have with the " I'll be there " I think works well as a prechorus. Maybe have no chorus between the first two verses and then after the second verse do that as a prechorus but then bust into a full chorus that is building the whole " I'll be there " lyric. This will also sound REALLY good when after that chorus builds up, the dynamics drop and it goes back to that nice groove of a rhythm guitar.
just my own two cents. Overall the song has a nice momentum and definate potential. Also, keep in mind that I was listening to this on my laptop speakers, so some of this could be a little skewed.
