I haven't had much experience with that song myself.
But as a general tip, look at your picture.
Where you have your guitar's neck horizontal, you are leaning over the guitar to see what your fingers are doing, your shoulders aren't even.
Consider getting the guitar neck up at a 45° angle, (headstock to the ceiling)
Keep your wrist straight, fingers curled.
If you need to look at your fingers, have your phone cam on in front of you so you can see yourself instead.
Someone with experience with this song is @supple steeple would have done great advice I'm sure.
