I love the idea of a Tarqim, but not for St Patty's day. See my other post about timing of seasonal Creatu.

I'd love the Tarqim to be the seasonal Creatu for Atquati but for Summer Solstice in June. Good time for swimming.
On my other post, I also think the Ebilia should be moved to the Chinese Ghost Festival in August. So that would give a balance of Seasonals in time and more around the world.
That said, I have some comments about the art work:
On the Teen, the tail looks wierd, more like a smashed backend.
And one more comment, the baby appears to only have two feet, it's hard to tell on the teen, but the adult obviously has 6. This should be more clear on the teen that there are maybe 4?
