I have to vote for Shroom. Vanilla is very versatile as well, but I personally think it can look at a bit chalky/powdery sometimes.
Ricepaper is nice (and I love it)...but I don't think it'll go well with your purple and blue e/s (it'll look awesome with Humid tho
).
So...if you only get to pick one...go for Shroom.
Or...if you can still find Femme-fi, get that one instead.
I
Femme-fi. It's the Shroom that I've always wished for. Way better pay-off and texture than Shroom.
