Undergraduate / I was accompanying the choir on the piano ; Common App/ Experience [5]

This is very very well written. Despite your personal concern for flow, I felt like I read this essays seamlessly and without any moments of, "Wait, let me re-read that to make sure I understand." The message about working hard to overcome arrogance is something that a lot of prospective students need a lesson in and I'm sure it'll be nice for the admissions officers to hear a story of someone who A) admitted their fault and B) worked to be humbled rather than just go on and on about how smart, creative, and nice they are.

Thumbs up.

(And a response to my only thread would be utmost appreciated :))

Undergraduate / Mama said we could fix it up; NYU-what intrigues you? [2]

From what I can see, it doesn't seem as though you're really showing much of a personality here. It shows that you are disgusted with your new environment, but you don't go into depth about why any of it disgusts you. Furthermore, your transition into your last stanza about it finally being enough is very prompt. There is no gradience of emotions leading into it whatsoever - it's just like, oh wow so now things are good? Try to add in a bit more of a transitioning explanation from where things are bad to where things are good for you.
