Chip... Download!!!
The first thing I notice is the volume. Its on the low side. When checking the general tab, i notice the sample volume is on the low side. Why?
Melody is kinda sad, which is in conjunction with the rest of the song. This is too bad, cus it kinda spoils the fact that its a chip. Chip's are usually fast and catchy. The bass and the drums are, but the melody structure isn't.
The bass and drums don't seem to change that much which kind of gets annoying over the song. I also miss treble in your song. Everything is having a dark image. The bass is really nice and deep, but there's no high part that keeps this as high quality. Instead it degrades it to become a bit muddy. You might want to either replace some lead melody samples by a sharper/higher variant or just play an octave higher.
You could also counteract this by adding short appregio effects every 8th row or so.
