Hi and welcome to the forums.

Really good song and I actually thought she sang it well in that key.

The track holds up well as it is, but if I was to suggest anything it would be to add some instrumental phrases, guitar or sax for example, in the longer gaps between the vocal lines. The other possibility would be some backing vox (ooh/aah} in the chorus to emphasize the pick-up from the verse.

Of course, all this is subjective and it's an excellent first submission.

ROG.
