The Maine - Perfectly Out Of Key Chords & Tabs

Standard tuning.
This is just the chords, The melody is relatively easy to figure out.
Sounds good to me, but I'm always open for suggestions and improvements.  

The intro is basically these chords, I add hammer on's/pull off's

Intro: C – Am – Em – Am - G x2
[ Tab from: https://www.guitartabs.cc/tabs/t/the_maine/perfectly_out_of_key_crd.html ]
 C                           Am              
Thoughts fall company and dreams as friends
          Em
I'm only half here
                Am    G
And other half pretends
  C
That I'm just
                  Am
I'm just a bad haircut
         Em
Some fashion from last week
           Am              G
No one really knows me at all
      C
But sometimes I like
        Am
Living in my own world
      Em            G
Disconnected and so naive
(pause)            
Perfectly out of key

Repeat Intro, continue same progression for the rest of the song.
