Portrait of Wakka, the Kingdom Hearts version, but two years post game (and thus a bit more like his FFX self). I worked really hard to get the 'official art' style down, which meant wrestling with a coloring style I'm not used to.
What's the thing in the background? The Darkness? A wave, I dunno. It's something that needed to be there for balance.
And yes, if you check the canon art, he -does- have an earring. At fifteen, no less! What a rebel.
