I really like the start, it's so calm and nice. You really nailed the tropical theme well. The bass that kicks in around 0:54 is kinda weird tho. Also the chiptune in the buildup doesn't really fit the start that well, and the drop sounds a bit weird due to it. Overall, the drop is pretty neat. After the drop, the section with the weird guitar-kinda thing is really weird, and it's kinda stupid and unfitting that it doesn't change notes until 2:22. I would also like to point out that this is very loopy, I'd suggest making more melodies so the song sounds different and isn't tiring.
Overall, really nice song. 4/5 :DD
