Mallow, uhhhh, I mean, uhhhhhh, you know

i guess its there roundness look and their personality

I mean, Mallow is basically What Rabbits Do times a hundred, so...

I love seeing the shenanigans Lil Boi gets up to

Arthur and Lil boi: the simplicity is goated on another level, and the sizes you draw them are my weakness
Heather: I really have nothing but Moth, seeing ocs of uncommon species is lit in my books

Not to sound incredibly blunt here, but... not quite sure what their character even is (Tho I've began watching this profile rather recently, so... ^^').

I'm just gonna say she's really damn hot, tho that's not to say the rest of what You draw isn't great either :P

T-tummy.... soft...

I'm guessing you are looking more for you completely original OC's, so i'll try and do those

Mallow- I mean her gallery would define her as probably the preggo oc go to, for her design I dont think she has any super outstanding traits except her versatility. You seem to like using her to try new clothing colors and outfits and such which makes me think of her in that way.
Tabby- Her pink color and pallette is very unique since its not a pastel shade, gradient hair is scary for cel shading artists but it looks nice, like a mixed drink
Nadia- Could probably use some more love! Only two pieces! ;w; Similar to mallow with versatility.
Arthur-Definitely defined by the bright yellow sweater, it makes him very recognizable.
Izzy- A very cold toned color pallette, combined with her lack of fluff seperates her from your usually warm toned palletted ocs.
Heather- I think heather is probably the more unique designs you have, with her fluff combining to the hair giving her a very unique sillouette. Big glasses are cute also, and none of your other ocs have eyewear so its very distinct.
Lil Boi- Definitely fits the bill for an artist insert. I think he serves his purpose of being "You" very well. Reminds me of my own sona since you started with a black/white Color pallette. Although im not sure of his species since he has some reptile-styled patterns now.

Sorry for the long comment -v-;
