I rarely ever critique art, but first I'll say that you've got great choice of color, you always seem to know what colors to choose, and the forms are great aswell!
Now for some suggestions, I agree with the other guy saying that your artwork could use more sharp edges, it can feel a bit too much with all the circles, which could use a bit more variety. Another is maybe you can try to do a bit of foreshortening and perspective, y'know to get a better understanding of dimensions and such, and you could try using more different shapes aswell, like with bodies and stuff, as it can give your characters more personality and stuff like that. Final one is maybe experiment with shading, make darker shadows and other stuff etc etc etc.
(I tried my best to be least harsh as possible, as I only want to give you more qualities that you could focus and improve upon. Hope this comment doesn't come out as rude.)

While I ain't that good of a art critic or artist (your art looks like God himself made it compared to mine), if I can say literately anything, maybe try adding a bit more sharp edges. Maybe it's just a personal thing, but your art is very Round, for lack of a better word. I probably could've worded this all better.

Well thanks for the compliment😂 and I get what you mean but I usually try to make my ocs look “cute” but I would like to practice drawing more “noncute” characters with maybe more sharp edges🤔
