We have a thread for it here: https://articulatedthoughts.com/threads/biblical-adventures.206/Looked at the D13 line. It might just be the soft goods but everything looks a bit too Buddy Christ Mego. I'm envisioning something more Frazetta Girls or Harbinger.
Almost all of the designs are based on classic Christian artwork and sculptures so it reflects styles from fairly modern interpretations to Orthodox iconography and renaissance paintings. A couple look like the "Buddy Christ" design mainly because that look was based on a portrait that became popular in the early/mid 1900's, which both D13 and whoever created that for Dogma used.
The soft goods was pretty much required though - both for potential posing and range of movement but also the owner wanted to build around a single buck and couldn't have produced as wide a range with unique clothing that was sculpted - typical for a small company. Soft goods always struggle a bit, but flowing robes/gowns/etc don't work in hard plastic. The expectation is the next Kickstarter will likely include a wider range of sources and stories - the owner did mention things like David and Goliath and is hoping to have a female and a larger male buck for the next round.
