First of all, I'm pretty sure you had a dick in your mouth while writing this-it comes out in the music.
Secondly, It sounds pretty good overall. Don't know what you made the sound file on so that may be the problem but would be better with some dynamical variance.
I award you 4.5 Stars with your above stated educational level in mind (one fresh out of beg music theory isn't expected to make a crazy-good-mind-blowing-world-renown-
professional-grade piece.
And last but never least, I like the note at 0:26.
