There have been three covers so far in Errant.
Chapter 0, which feels weird now because the early pages and cover don't quite match how the style ended up. But design-wise it did set the style rule for chapter covers.
Chapter 1, where I knew what I wanted to make for the cover ages in advance. "The bad guy won and everything sucks because people don't even realise how angry they should be." Stupid sexy Urien! The banal "lifestyle" article titles were the most fun thing to come up with here.
And of course, the main series cover. One of the biggest influences was the iconic fountain shots from the opening of Friends, where it's like "look at all these cool weirdos!"
BONUS: The scrapped series cover I drew, then decided I hated. UGH it's so awkwardly proportioned.
