The work of concept artist Nate Hallinan is, hands down, some of the best art I've seen another human create.
Okay, that is a bold statement to make, but the characters he develops and the stunningly rendered visuals of the locales he surrounds them in are obscenely realistic, fully realized and just down right badass.
Take his Legend Of Zelda art for example, and his imaginings of those disgusting Skulltulas and the heroic and introverted Zoras. The work he creates is sublimely fantastical and hyperrealistic, but somehow manages to retain a sense of grounding in the real world.
I would've loved to have visited Hallinan's Hyrule as a kid, and after seeing these you would've too.
