Great lead vocal.
Listening to the second mix I found the harmonies distracting. First the harmony vocal was panned left, then right, then both. Harmony vocals don't typically bounce from side to side.
May I suggest you use the same number of harmony vocals throughout the song and pan them near left and right. Imagine multiple singers surrounding a single microphone. They tend to blend together into one sound. Presently each harmony vocal is too distinct.
This is my opinion and should be taken lightly.
