In short, basically you find everything's true form to be gigantic. Bizarre, but ok. Also totally untrue.

God's true form, well I'm not sure what that looks like in Supernatural, however it's got to be intense, memorizing, and holy.

Horsemen's true forms, not really sure how to explain it, I know they each have one, but that's it. I take it there true forms may similarly resemble this,

No, Eve's no giant. She's probably human-size, only hideous and deformed, as implied by her face.

Yeah, I can see Leviathans being that big.
