I was working on a different profile picture for my main account- Why is this so cute-? Can someone please explain how I made my character more cute in this-?

So, I made a upgraded version, because why not-

(Okay, somehow, I love the hand for no reason- I have no idea on why I do- And I decided to make a picture of my character's costume as well, it's surprising, because I'm also going as The Squid Game doll in real life-)
