1st impression - that 1st chord is sudden and a jolt...I can't say if fading it in would be a good move but something that fits the gentler vibe of the song perhaps.
The extra voice adds melody & texture to the song - sort of a Leonard & Judy thing.
I was going to comment about the song not being about a US city but Berlin was almost an exotic cousin of NY before the wall's fall.
Loved the song.
