Hi Tom,
What a place to play guitar. I have the airing cupboard behind me - you have paradise!
Sounded good to me
I think what i picked up was a certain tension - probably red light tension. it can be hard to relax when playing and recording - fear of mistakes, etc.
My advice - what does it matter if you fluff a line?
Make a mental note, but keep playing through and try and correct it next time.
All the best,
Digger
