I love the ornamentation and that one pitch bend you did (I love those)
Kudos for keeping within the boundaries of 8-bit counterpoint. I've always found it hard to express creativity in my music with only 3 voices (have yet to actually do it.), but you've managed to pull it off wonderfully.
Its true talent like the composers of the 80's that could make a memorable tune with such a narrow box to work in, hell its like Beethoven and Haydn.
