As someone who is familiar with this song (and a pianist as well), I have to say, right off the bat, you've got really good expression with your playing.
The arrangement is short, for starters, and doesn't take into account the second verse -- "And feelings like I'd never lost you", or somesuch. That's quite a disappointment for me.
The broken chords are fine, but... try and see if you could go past that. I don't know why, but after hearing broken chord left-hand parts from so many people, I tend to associate that with those who have only played for a few years -- and the whole point of a cover, especially if it's your own, is to go past what everyone else does. That being said, you've already stated that the arrangement was by someone else.
Which leads me to the question: why don't *you* arrange this song? 'Feelings' is an amazing song when done with simplicity in the beginning, and extravagance in the choruses, building up in the verses... Because the cover doesn't have your take on the song, I can't rate it as high as I would rate an outstanding cover. I'm not here to look for someone's version of 'Feelings' which already exists and has been already covered before. I'm here to hear *yours*.
