Nice arranging, it's above average as far as writing goes. The sound is a bit cheesy but since when is video game music not? I wouldn't promote a midi piece as Acoustic though clearly at some points you can doublethink yourself into believing that you are listening to an Acoustic guitar. Of course, then you'll hear a rapid fire succession of notes that gives away the midi nature of your stuff, or you'll just exceed the guitar's range and it'll sound extra-tinny.
However, this was very well done. I look forward to hearing what you do with multiple instruments.
