My first chiptune

...sorry about the wall of text, ChipMusic mussed up my formatting.

Hi there! First of all, welcome to ChipMusic and glad to see you're interested in the sound ^^

Here's my attempt at some CC:
After listening to your module, I can see that you have a few nice ideas laid out. You may want to expand on these ideas and then arrange them into sections to form a larger song (do a search for song structure).
Another note (which I am also constantly guilty of): your rhythm & bass section is solid, but you may want to mix it up a bit to avoid sounding stale. Even pizza gets boring if it's all you eat ;P
I also noticed that channel four in patterns four and five switches from C minor to C major, which was a bit unsettling for me.
Not sure if that was what you were going for or not - dissonance can be a great tool, when used skillfully!
If you have no clue what I'm talking about, don't worry. Music theory isn't VITAL to writing music. It does certainly help, though, and you can learn a lot online.

Anyways, yeah! You definitely have some solid ideas on your hands there and you obviously know your way around a basic tracker, so you're on your way to writing some great stuff!
