Twenty One Pilots - A Car A Torch A Death chords

One of my favorite songs ever by probably my favorite band. I figured it out on piano 
then transcribed it to guitar but I might need a little correcting or i could at least use 
some ideas of how to make it better so comment please!

Capo on 3rd

Not sure of either of these D chords, whether they should be a little "special" or both 
just a regular D chord

      D-alt     D*

    G                             D-alt
The air begins to feel a little thin
     D*                           A
As I start the car and then I begin
   G                         D-alt
To add the miles piled up behind me
  D*                           A
I barely feel a smile deep inside me

      G                                D-alt
And I begin to envy the headlights driving south
          D*                             A
I want to crack the door so I can just fall out
     G                              D-alt
But then I remember when you packed my car
    D*                                  A
You reached in the back and bucked up your heart

    G     D-alt D*   A
For me to drive away with
  G        D-alt    D*
I began to understand
   A         G
Why God died

G D-alt D* A
[2x]

    G                            D-alt
The demons sat there waiting on her porch
         D*                             A
It was a little dark so we held a makeshift torch
    G                          D-alt
And when my car was far out of sight
   D*                                         A
He crept in her room and stayed there for the night

           G
And then I felt chills in my bones
             D-alt
The breath I saw was not my own
          D*
I knew my skin that wrapped my frame
        A
Wasn't made to play this game
            G
And then I saw Him, torch in hand
            D-alt
He laid it out, what he had planned
           D*
And then I said, I'll take the grave
              A
Please, just send them all my way
[2x]

G D-alt D* A

  G        D-alt   D*
I began to understand
  A
Why God died

G D-alt D* A
[2x]

    G                            D-alt
The air begins to feel a little thin
         D*                          A
As we're waiting for the morning to begin
G                                D-alt
But for now you told me to hold this jar
           D*
And when I looked inside, I saw
         A
It held your heart

    G     D-alt   D* A
For me to walk away with
  G         D-alt  D*
I began to understand
  A
Why God died

G D
