This is a fairly simple port, and as such, I'm being a bit more strict on it. It's off to a good start, but I think you can do more with the instrumentation.
Given the simplicity of the song, I think you could combine some instruments to make everything sound fuller. One suggestion I have is to make #3 @6 instead of @0. This will sound closer to the original.
Another suggestion I have would be to copy #1 and #2 onto #4 and #5, and make each set of channels (#1 and #2, #4 and #5) a different instrument. One example combination that might sound good is @1 and @2, but feel free to experiment and see what sounds good to you. Make sure to change echo/volumes accordingly.
The original also has a fake echo that plays the lead slightly differently, but honestly, I don't think you'd necessarily need it. Up to you if you want to add it.
Also, there is a wrong note on #2. f1^1<a>cd1^1fga1^1de should be f1^1<a+>cd1^1fga1^1de
That should be it. I look forward to the re-submission!
