Ha I have no idea how I didn't notice immediately how weird his eyes were.
filled in the details, moved the eye down.
added in details and background, moved some of the features around of photoshop to make them look more like him.
I was going for Earth and Dry, but for kicks and giggles I made another with him as Earth and Fat.
Did a bit more work to add in the fat effect.
here's a detail of thin Ian's face.
