Thank you very much for the comment! Yes, I plan on doing stuff to the mixing and possibly have more of a melody as you mentioned. As for the ending; yes, the entire piece is in the key of Cminor but I thought it sounded interesting to end on an E note (imply a Cmajor chord). It just added an unresolved effect that sounded cool in my opinion but yes, I can see how that doesn't really fit.
