omg gurl your lineart is really confident; like it's so clean and CRISP and not like shaky. do you use photoshop?
also wow cute style 10/10
uhhh shit you asked for a critique buuut i know it's a chibi style so there's a lot of stylization; the only thing i can think of is maybe try erasing the lines from the eyebrows that are under the hair? if that makes sense idk. i've gotten into the terrible habit of keeping the lines under the hair and i've noticed that things look a bit cleaner when i get rid of that.
buh bullshit critique is bullshit anyway this is cute as hell ok
i use sai because it has a line stablizer, photoshop is a bit slow for me! and yeah i usually do erase my eyebrow lines, but i figured since it was so stylized i'd go with the super anime tradition of somehow layering the eyebrow lines with the hair and yeah in retrospect that didn't really work out as well.
