It's always a treat to encounter another Jet Force Gemini fan. Still one of my favorite games on the N64; and perhaps one of my favorite shooters I've ever played. The music is also one of my favorite soundtracks ever, and may be the best sounding to be heard on the N64.
I'll be honest, while the arrangement overall was great, there were little things that kept me from a full 5 stars. It felt lacking in bass or counter melody at times, like at :16. You fill in with more voices at :25, then drop away again for the following phrase. There were also a few times where I felt the melodies or instruments were ever so slightly off the tempo. Lastly, some points in the song lost the dramatic or stronger moments, like at 1:25; there is much more force and power in the original. While I know all sorts of liberties can be taken to make a piece your own, this one felt like it tried to recapture the power and instrumentation of the original, and so missing these elements brought it down slightly in my ears.
Do not misconstrue this review as angry or the piece a failure, though. I'm ecstatic you arranged it, and the piece still sounds like the S.S. Anubis, and the instrument choices are great. Little things just keep it from perfection. But this is pretty close, though. Good work.
