Where I End And You Begin Cifras

I wanted to play this song with chords on acoustic so I came up with these after
listening to the track. I think this is a decent 1st attempt at putting this song
to chords, but I am sure you all might add to it.
 
Capo on 3rd Fret.

               Am         Em                         Dm      G
There's a gap in between, there's a gap where we meet
             Em        Am      C    G
Where I end and you begin
             Am         F          C                G
And I'm sorry for us, the dinosaurs roam the Earth
       Em           Am
The sky turns green
             F            G        Am (add bass riff w/pinky)
Where I end and you begin
 
     Am          F                C             G
I'm up in the clouds, I'm up in the clouds
         Em       Am             F          G
And I can't, I can't come down.
        Am                         G
I can watch and not take part,
             Em                         Am
Where I end and where you start
           C            Em        Am G              Am (can add bass here too)
Where you, you left me alone, left me alone
Am                   Em              Dm                 G
X will mark the place, like a parting of the waves
             Dm     C                 Am G            Am (add bass w/pinky)
Like the sky falling into the sea, into the sea.
 
[play Am with pinky bass riff until next part.]
 
         C (add bass riff w/ring finger...similar to pinky riff)
I will eat you alive (4x)
         Am (w/bass riff)
I will eat you alive (4x)
 
[repeat C and Am lines until you feel like ending--I end on Am. I also play around
with the pinky riffs for variety.]
