I enjoyed the first part of the song... after the surf tune, kinda reminded me of a strange B-52s bit. I think my favorite part was actually the slowdown at around 2:10. The whistle with the strong ... violin? stabs was fun. I did think it ran a bit long at the end, maybe by 20 seconds or so, but overall, I enjoyed it.
I like the first part of the song alot, but I think when the main chorus kicks in, it should be... fluffier? Lighter? It seems a little hollow compared to the warmth of the intro. The background music takes over that hook, which should (IMHO) be the strongest part of the song, as it's probably the most memorable. Anyways, I like the start!
