In your art, I see your love for OoT in its entirety. You include details that would be cropped out of most fan works, such as the Octorok you hid in the stream below the Gerudo Valley Bridge. Then there's Grog -- who is often forgotten -- and the Water Temple, which a lot of people want to forget.
You display more than one approach to fanart, but that element is what I was referring to when I mentioned unique-ness. I hope that makes sense! I certainly admire your other works as well -- your Link's Awakening piece is particularly gorgeous.
