The song builds really nicely. I like your choice of your instruments too and the ending is nice but i feel like there isnt enough dynamic in the chords as the base lingers on one note for the entire duration of the song. I realize this might be deliberate and if so its great! I just personally feel that if your making a longer fuller piece (which i assume is the intention here) its important to keep the pathos fresh through a powerful change of melody. It helps move the listener.
Either way 5/5 great work.
and it loves you
