A size comparison showing the feral versions of Ann, Winston and Syrus

Their forms are based on this sketch of a feral Curis. (meerkat-like species)
And much like their humanoid forms. Ann, being the youngest, would also be the smallest.
And because Syrus is based on a Chinese crested dog. Some minor elements were also added to this, such as the fluffy(ier) tail and slightly longer hair
I was going to put them side by side, but it didn't look quite right.
And, once again, like to note that only those who have green eyes can change forms (between humanoid and feral)
As such, both Winston and Syrus can not do that, but I went ahead and made one for the two anyway.
