I like the idea, I see what you were going for, and you seriously have two choices here:
#1 Keep the "sound" you have there, and embrace the actual result, which is not very R&B but more elevator music like. Not a bad thing really. It's a musac feel that is quite unique, and when using Zelda and Chrono Trigger, you have to go for a unique feel. The piano at first is too dry, you need to find a way to give it more presence, but everything else in there somewhat fits. I love it's cheesy vacation resort / musac feel. If you can embrace the cheese, this could be a very unique thing.
2# Keep the idea, start from scratch. As an R&B type song, I'm gonna say you somewhat missed the mark. Strings for this type of sound seems wrong, or maybe just used wrong. The piano, in this case is not only wrong, but prohibitive for the R&B thing.
My honest opinion:
Embrace the cheese, please do, you may have stumbled upon something that is gonna become very memorable.
