I like the overall choice in instrumentation and your mixing is pretty good. However in terms of originality it's quite identical to the original.
Gotta say though, I'm glad to see another fan of FF6 and especially this song. It really is magical, isn't it? :3
Overall, I like it but I think with some more time devoted to it, you could really remix this into your very own interpretation and give it a unique feel.
Keep em coming and lets hear some more FF6 tracks if you plan on further VG remixes!
Please contact me if you would like to use this in a project. We can discuss the details.
