Nice.....
The intro gives a very nice build-up, and the chipsounds match well with the calmer intro theme, along with the atmos-sounds in the back. The chorus is a little weak, choose phatter drums I'd say... Also I would lower some of the notes one octave in this piece, super high-pitched chipsounds are annoying and cut the ear. Still, very nice for a first 8 bit song, keep it up!!
