Even without having heard this theme before, having played many JRPGs, this brought a lot of nostalgia for me. I feel like the playing was well done, and the recording quality is good as well. I do wish you had a little bit more variance with either pacing or volume.
Whether to do so to emphasize existent nuances of the piece, or to put your own spin on it, it would have made it more interesting.
0:15-0:21 for example seemed (take this with a grain of salt) like it could have been a bit more dramatic in volume.
