I went for a sort of earth-themed-Zora look for this guy, as you can probably see by the nose and the eyes. Did you ever play Majora's Mask? The Zora swimming sections in that are incredibly fun, they got a great feel for the momentum of it. Maybe it's an unconscious coincidence but the chunky golden swords remind me of the big weapons Ganon has in OoT.
This one's a back-and-forth mix of Photoshop and Paint Tool Sai.
