So, you've made it to the final round. You've clearly proven yourself. Time to judge by NGADM standards - scoring will be harsher as a result. In any case, here are some pointers for improvement.
The Good:
-Whoah this is a warm mix, though it really fits. The drums are super clear in this too which is great (aside from the toms but those are a bitch to fit).
-Once again, great chord progression and overall organization of your piece.
-Great drumming in this! It sounds extremely natural.
The Not-so-good:
-Well, this is really warm mixing, but there's one thing that could benefit from being more bright - the NES sounds. They're very much buried as-is. Heck, even the cymbals are somewhat buried as-is - it sounds almost like everything was filtered down and/or put into a lower bitrate. You even use some of the higher end sound later around 3:30.
-I think I mentioned this last round, but you could really benefit from having more of a clear melody. You also have all of that high-end space in your mix which you could use for it.
-Ending ends. Not very interesting ending and not much of anything indicating that there will even *be* an ending aside from the fact that it had been playing the same idea quite a few times and the timestamp on the music player.
Final score: 8.5/10. Very good piece, but not quite as good as your second round piece. You're a really good guitar player - some excellent electric or acoustic guitar runs in it would be absolutely fantastic and really lend some extra interest to your pieces, even as good as they are now.
