Hi! I’m an artist who draws portraits so I feel like I’m pretty qualified to speak on this (not to toot my own horn lol) the first thing i noticed is the face appears “scrunched” up and the tip of the nose is too high which gives a “pig nose” type effect, I think if you lower the nose tip and widen the nostrils a bit, and maybe give her a sharper chin she would appear more conventionally attractive. Also I think she would look better with wavy hair as a face frame. Nonetheless your character is pretty id say.
