That was unexpected
I was expecting this to sound like there was a lot of action going on or maybe a dark tone to it. I just expected that from the fact that it had "wolves" in the title. This is actually an extremely soft and soothing melody. It probably helps that I used to play the piano all the time when I was a kid. Everything was so precise here I could just imagine myself touching the keys like I used to. I can understand why this would be a favorite version of anything.
It is just such a casual song and it can be played when you're doing any mundane activity. There's no attempt to be flashy or zany, just a nitty gritty piano tune. It is also a very original style. There could be some more base sounds but it's really all you need for something done entirely on a piano. I believe that is what you did.
