You know, you've definitely got an atmospheric thing going on, and you have good variety in your mix in terms of composition and melody. It is different, but it is very good for being new to the chipset, and I can always appreciate when people try to use FM for the drums as then you free the sample channel up to do some cool stuff (SNES melodies anyone?). Although sampled drums are good sometimes as well.
This has got a retro sparkle to it. Yes, it does sound like Road Rash instruments, which I used to play as a kid.
May the best chip artist win!
