Unlike a lot of other graphical hacks, this one is fairly consistant and pleasing to the eye. A few things stick out though, one being Link’s sprite, which looks a bit weird, particularily the ears. I think it would be benificial to use a model that more closely resembles what he looks like in Link’s Awakening, like some of the enemy models used in this hack by the looks of it.

And the grassy overworld tile is repetitive to look at. Of course, Link’s Awakening used this tile a lot, but it also had a variation of other ground tiles to go along with it and add variety.

Also, Link’s sword blends in with the ground in the overworld; not only does it not look good, but it makes it hard to visually judge the sword’s reaching distance in battle.

With these things fixed, this could easily be a top tier Zelda 1 graphics hack.
