hrmmm how i improved in art was me getting fixated on 4 characters & drawing them almost everyday for like 3 years... u rly need that drive and bc ur fixated on these characters ull want to draw them in any way u like so like along the way ull want to learn how to draw stuff but also Like. if you draw everyday without having a goal of what u want ur art to look like and u dont critique ur art and look for areas to improve upon ur art will remain stagnant no matter how much u draw

ill also attach an img of an old answer too...
