Heres my entry on the challenge.
Although the hat's shading bugs me, great idea!
Awesome idea, my fave so far, but your shading needs a bit more time - it looks like beard stubble and skin discoloration. Maybe try dithering in the shading a lil' and a better outline on the face especialy the deku side + a solid dark green or black outline of the hat. There's too many lines in the top right corner of the background and it pulls attention there and doesn't look like the movement of the rest of the bg.
It's very flat, but my work is the same.
Why is the hat shaded like that? that's not good shading. And regular link is missing an ear...
