zero, close every manga u see...
try to read carefully every nice and harsh feedback u got.
all of them got points but u just pass over it, then u continue ur drawing just the way u always do which i think therere no progress in it.
imo ure not yet have right to step into mimetic style, thats why i told u to throw ur eyes out of ur manga.

since ure a animation student, u should understand...
grab your pencil n sketch book then head outside, take a comfortable spot to sketch.
dont abruptly starting sketching, observe the scenery in front of u bout few minutes,
determine ur eye point after u decide on ur drawing object.
u do not need to finish every figures (living or non-living object) on ur sketch.
just draw some frame of those object but make sure it clearly show the movement.
dont take photos or ur sense of volume will dull.
when drawing movement, better avoid cubicle frame, curves line make a better result.
in next few days you can finish those sketches.

i recommend u to not copy any manga style drawing in a year.
just focus on frame base drawing, it help u learn to scale and help u to understand anatomy + movement better.

the way u draw the lines, excuse me but it is ugly,
it show how hesitate n inconsistent ure. please be more brave and confident.

therere some training u can do indoor if u still eagerly to copy a manga style (which i dont really, sigh)...
buy a bunch of tracing papers, trace every drawing u can found.
try to limit ur time when u trace. 10 A5 tracing a day at ideal.
i guarantee u can make ur line smother n ur anatomy more valid.
after u can grab the feel of drawing, u can throw those tracing paper n those drawing examples.

i encourage u to not copy,
since ull become limited if u dont have example. ur imagination definetly walk in narrow road.

gud luck,
since nine years of my lazy drawing learning only get me a lil better.
