I like #33, though I might want to move to a bluer purple and perhaps a browner grey?
Eggplant/Aubergine for the purple and maybe a tree bark grey/brown? (With that chartreuse leaf, love it.)
Would you mind exploring a bit with a slightly more earthy font for one or the other of the pieces? I'm thinking leave poetics of healing as is and make deep medicine font more ... (I'm not good with font picking but ...)
These are all very different from each other...
