I've really enjoyed Home Sick Pilots so far. Image Comics book about a girl who encounters a haunted house that turns into a ghost powered wooden mecha.

Definitely over the top sometimes, but the ghosts are also horrifying.

EDIT: first one is free here:

EDIT 2:

Also Monstress, I'm behind on it, and don't remember a ton of plot details, but it's a pretty dark fantasy story with art that consistently looks like this.
