I love piano music like this :D
It reminds me of Kingdom Hearts, which is never a bad thing. It also bears some resemblance to "Love is Strong as Death" by Phonometrologist, here on Newgrounds (For example, 0:29-0:32 here reminds me of 2:26-2:29 and 5:17-5:20 of his piece). And that is one of my favorite pieces :)
I love your chord progressions and melodies here. The piano sound is very soft and sweet too, so the Christmas feel definitely shines through. Thanks for sharing! This definitely earned a spot in my favorites :D
