When the first samples of platypus made there way back to Europe, they where assumed to be a taxidermical joke.
That said, what a lovely kinship you have made here.
It appears the matriarch (?) is coming form a burrow which raises questions about horns catching and such, but a wizard did it, or the horns only appear in sunlight, or they shed them in fall like many antlered species and are only subterranean after that as spring and summer are mild and safe.
ooop sorry, got a bit caught there, in any case the little details you tuck in are very nice.
Like the two little ones on the right studying each other, or the development of the adult muzzle and the wing tips and ear tips being illuminated.
It is all quite lovely.
Thank you for making this.
