How can I improve my art?

[hollow current]

I'm struggle and need some advice 🙂 Someone said that my problem is in my lineart. But how can I improve that and is there anything wrong in my art?

ur really good at rendering but anatomy needs improvement

and usually lines are what we use to really show the anatomy in a drawing so thats probably what they meant

since your lines are the scaffolding to your drawing that tells you where to put the colors

if your lines arent anatomically accurate then no matter how good your colors are your drawing wont look perfect

the girl in the third pic looks amazing tho

everything looks right
