the piano and the base drum was a nice choice.
and liked how you kept it all fresh with altering the tone with different instruments but kept the same note structure
i would have increased the electric guitar at 0.45 a few octave to have a greater build up of emotion in your song
i would have dropped the electric guitar at 2.00 through __ a few octave to create a stronger visual for a downed part of your song, coupled with the slowing down piano would make a nice comparison as well
Also then think about adding a climactic note at about 1.50 to signify something has happened to something or an event happened to create a deeper feel to the song
It's a very well done song as it is, but id be interested to see the story that you are trying to put it to,
especially since as it stands it has 2 down sections with a electric guitar,
