Ok, here are the few points that I could find:
  • Window angle with wall - The stained glass windows have an angle to them, but the walls do not.
  • Blood smears not "scaled" - The blood stains/smears/pools look more like they are droplets on the page rather than part of the interior of the building.
  • Floor tile too "bathroom" like - I really don't like that floor tile. A church like this would be more ornate and certainly have a floor that their god would be proud to look down upon. This floor look more like a dingy bathroom tile, or something slapped together by those that don't care what it is made of. Perhaps larger tiles with a lighter color/texture and much smaller joints would improve that.
