Minorly repetitive but original
Though had varied parts, within those parts it semmed repetitive. It sounded a bit empty because you were not using the full range of the piano, or the keys you were within. You might have been shooting for that empty sound though. But in my opinion you could have fille din the gaps a bit at some parts. Nice little medley overall though.
thanks :) ... yeah, it was originally for a videogame so it was composed to fit a scene :P... thanks for the comment though :)
