How come you didn't pan anything? Why not pan the vocal and guitar 15 right and left?
Was this all 1-mic tracked - rhythm guitar plus voice one track and lead guitar plus low backup vocal 2nd track?
just need to make it more ear candy for your listeners.
I can hear two voices going. You double-tracked yourself? You don't need to. Your voice is good enough without doing this.
In addition to what others said about the guitar, it also sounds a bit out of tune.
The guitar could use some EQ. It sounds a bit harsh to me. Seems like the guitar itself may be a pretty bright acoustic.
What did you record the song with console/microphone wise?
Does it need drastic EQ or just some problem frequencies? The guitar is a Kasuga from the 80s. It was a salvage from a hoarding house. I was gonna make it an experimental guitar but used it to record this song anyway.
I used an MXL 991 into the Alesis FireWire console, which then recorded into Cubase. I have a very beginner set up.
