writing while i'm listening.. the sample sound is really good, perhaps could use a limiter for the highs to not distort, but it's like something The Fugees would do.
i tend to feel this way alot here in these forums, but the sample loops go on for way too long, alot of people don't like constant repetition... i would've made a similar sound or something that compliments it to sway back and forth, y'know, really play with the rhythm.
Here's an R&B tune i can use as a bit of an example, i have a really smooth pad in there and use it alot, but when it drops and it takes a break, it's relieving, and then it comes back:
