I would try basing it white. Then perhaps a pale pink. Apply a "red ink" instead of a red wash, should dry with a slight glisten and look like a fresh-flay. Then highlight to taste I imagine. Depends what you want as the end result, I like the flayed wracks but kind of want them to look a bit more gruesome and fresh! Inks are also great because they will pick out the recesses of the model and leave the raised bits auto-semi-highlighted!
