As Lead Campaign Artist I oversaw the env art creation of the Chaos Realms on the Realms of Chaos Campaign for WH3.
Simon Pennington and I worked together to drive a lot of the features through that were shared between Battle and Campaign. We also worked together with Concept Art to bring the lore to life for WH3.

The env art creation was very much a combined effort of all the campaign art team.
