Only tested one so far. Forced In: Main tone could be clearer (i.e. more treble, less bass, tiny bit less mid). Some sections, notably the delay tone acoustic section, have notes that seem correct, but are not locked to the tempo map. Tremolo picking section tone could use a lo-fi pedal. The F# minor chord frame could be a little different (by not barring the 2nd fret, it would allow for more control over vibrato), but that's just a little thing. And never forget to cut your preview to 30 seconds and fade in/out. This should be a requirement for all future updates! :P
