Just from the cover i see a few flaws
No matter what the EoW fight is impossible. Building a coliseum like that cant happen, and if thats a village, it cant be because the corruption cant be a village. Its not a obvious corrupt area (MAJOR FLAW) Dryad wouldnt follow the Titanium Armored Terrarian, and that mountain the EoW is coming from CLEARLY isnt corrupt, nor is the eater THAT big.
Also he has a green stomach, but i cant vouch for this as he was never shown with a open belly.
Do you really expect the comic to read absolutely identically to the game? Its a story telling medium, not an interactive video game, its going to have differences.
For what its worth, the cover is just decorative; in the actual comic, all of the fighting takes place in the Corruption. You know what they say:
