Okay now that I've listened to this for a while I will try to give it my best attempt of analysis.
Firstly, your opening is kind of deceiving - it sounds like the beginning to something hopeful or happy. Maybe this was your intent, to signify that the day started out ordinary, but it does seem misleading.
As you as your transition into a episode that sounds "minor" it starts sounding very dramatic, and kind of beautiful in a "exotic" way. I love those little zig-zag like passages in the right hand - (around :40) they are very beautiful. I think you could write an entire piece based around those little motifs.
The chords you use during this section aren't melancholy in my view, there more dramatic, reminded me of Mozart's Moonlight Sonata 3rd mov. in a way - very dramatic.
The majorized chord at the end is kind of a surprise ending, i was expecting a major or minor 7th/9th chord.
I think this piece is very good actually, except that it's way too short. By writing a fully developed beginning middle and end this piece would transition a lot more smoothly and feel more complete.
In all, it has a lot of potential. Good work.
