My Death Guard transfer sheet finally came in! A bit of consideration while staring holes at the transfer sheet, then making uncomfortable amounts of eye contact the Black Books, then the being real happy strangers couldn't see me examining their Death Guard in detail over internet, I came to the decision that I had to lighten up the Castellan Green. I mixed in a bit of Pro Acryl Olive Flesh.

Central is just Castellan Green, the left and right are the lighter version. They'll end up a bit darker after the oil wash.
