Audacity Blue Yeti



I am starting to compose my solo piano pieces but I'm having trouble recording. I would like to know how to get the best quality using my blue yeti mic and audacity. I know this mic isn't great for recording the piano, but there have been recordings that have surprised such as this one:

I don't know how he made such a great quality video using this mic, but i would like to find out.
I believe the problem is the laptop that I am using, I'm using a Chromebook (probably one of the cheapest laptops out there) and it is running on chrubuntu so i can use audacity. It also might just be a piano problem, I'm playing on a winter upright piano that hasn't been tuned in about 7 months. You guys have any ideas on how i can improve the quality of my recordings?
Here is a short recording of me playing some improv in Bb min:
