Glad to see someone tackle that one. More Zelda 2 is always welcome!
As usual, keeping track of your wips versions when they all have the same name is my worst nightmare.
This one seems to be number 4 though...
The original melody is extremely catchy, making it easy to integrate into the mix and to rely on for a melodic hook.
Though I'm not convinced by the sound choice in the begining. Plus the empty atmosphere doesn't really work in your favor.
Try using some cross-delay on that harp, and adding alternative rolls and plucks to give it a more realistic/humanesque feel.
Also, it may be interesting to vary slightly the original melody on just a few instances.
You've got a very full sound overall, with a tight prod right out of the bat.
The part from 0:45 has a Castlevania feel to it, and I dig the distinctive sound you have here.
It's slightly different from the usual tone, while retaining your metalcore trademark style.
It fits the song prefectly. Really great sound you've achieved here.
At 1:05, the lead should deviate from the midrange and go tackle the highs more, the way you usually do it in your solos.
The synth directly afterwards sounds cool in itself. But it doesn't blend very well with the instrumentation.
However, it blends in nicely with the production. So it's not so much of a technical issue than it is an inauspicious sound choice.
I'm not the expert on electronica by all means, so I leave it to more synth-savy people to comment on.
And at 1:52, the harp returns and makes the simple melody layered on top of a thin soundscape more obvious... and kinda out of place.
Also, during those parts the drums/toms sound a bit dry and sparse. Add a few more occurences, and raise the room reverb on those.
Finally, 2 minutes 41 seconds is short. I'm sure you could easily extend the song to 3:10 or so.
Some more work on sound choice/design as well as pushing your mix a little further should hopefully bring you closer to completion.
This is a good mix with nice prod and great potential. Now make it awesome!
