Very nice melody as always, but still lacking some human elements to it, but that´s understandable. The holiday spirit is here for sure!
I like the notation. It's pretty happy and sincere. Mega does have a point in saying that you should humanize the notes a little more, just for the sake of that added realism.
I think you should keep this for later and fill it in as you go. I hear the potential of what this can be and I think you can run with it. Purty gud, I'd say :)
P.S. - Skill comes with time. Keep working at it and you'll see yourself flying through songs and laying down ideas with ease in no time!
I don't like how every note is the same velocity. It'd sound a lot better and more human if some notes were harder than others. For what this is though, it's pretty good.
