i think its an interesting composition! its pretty neat! In terms of lineart- you might wanna look into increasing stabilization on whatever pen you are using. it depends on the software on how to increase it. for dynamic line weights- i tend to go back in after completing my regular line art, just so i can see where to place thicker lines.

i think your lighting is pretty good as well, i would focus a bit more on your shading on the character- the eye shading seems a bit odd (particularly on how it interacts with her hair). I think you are trying to go for the eyes showing through the hair, but i think your opacity might be a bit too high!
let me know if like this doesnt make any sense and i can try to explain further! also trying pushing the limits on your lighting and i think you'll get much more interesting lighting! (like bigger shadows and harsher lighting)

i think thats really cool, overall your art its pretty goods, but if i can give you an advice, maybe you can make the lineart more brave or you can give a more shade in your eyes so your character can be more stunning, bcs i think the line art was really thick😙🫶😋🫨
