got improvement?

i been drawing since i was in primary school,i still remember the first time i drew a human (i drew her hand at her waist XDXD ) but i was proud with it.Then come along sailormoon,it really influence me a lot and i decided that i want to become a mangaka
well,now i slowly follow my dream but i promised myself,before i archive my dream,i need to improve my drawing skill a lot
I never attend a drawing class since that time the drawing class near my house the fees is expensive >.> so i self-learn everything
i noticed that i have the ability to copy certain style of artwork if i stare at it for hours ( i can stare at sailormoon character for hours and my drawing will slowly copy the style)
so,i try to avoid that since i searching for my own style.

now,after more than 10 years i non-stop draw,i think i already found my own style that i am are proud of,but still need a lot more practice
so,i included a comparison my old artwork and my new artwork of my first OC character

featuring Kanako Uesugi from my first manga entitled 4 powers.

i lazy to ink the new one,so,here you are,just a sketch XD
