While I’d love to see all the mane6 done as lamia, I think a little variety would be in order.
Twilight Sparkle: lamia (as shown)
Fluttershy: I normally pin lamia on Fluttershy if only because of her stare, but I guess we could go with perhaps a phoenix griffon (and accidentally incinerating herself whenever she gets scared)
Rainbow Dash: got a soft spot for Rainbow as a windigo
Pinkie Pie: funnily, for all the ponies I’ve turned into changelings, Pinkie Pie is the one I’d really consider enjoying it to its fullest
Applejack: really can’t beat Timberjack
Rarity: siren, definitely a siren
