Hey you're totally right! But it's so hard to keep consistency in the rhythm of this tune. Haha, and yeah, I totally used this argument, but it's kind of ironic, because I know it would sound much better if it was perfect. (If perfection really exists).
And I have to say I'm always trying to give the best of myself. I practice way more than 15 minutes everyday, but on a lot of different tunes, some song, some covers, some originals, other music instruments, skateboard, juggling, painting, and tons of different activities. So you surely can understand that it's difficult to keep a consistency.
For example, I was able to play this tune really well 3 years ago, but forgot it a bit with time... I should maybe had trained it a couple weeks again to get it properly. But it just went through my mind like "Oh! I forgot I learned this song long time ago. Let's try to film it!" I was also thinking: "Who cares if it's not perfect, it will maybe motivate some people to play it better than me?"

I'm honored to get a such critical and constructive feedback Catherine. Thank you! :)
