Improving on art is just like anything!
but don't give up if you ever get frustrated just take a break! you'll become good in your own eyes in no time!
it takes time to warm up and adjust to your style
if you are worried about being unique and have yet to find your techniques don't worry it just kind of happens and comes to you when the time is right!
for improvement, it's purely based on how much you practice
it depends on what kind of drawings you do but from your profile picture, I'm guessing you do anime! same!
to answer your question:
follow online tutorials (they might seem dum but they are tactful and can be applied to your drawings if your that committed to work on them)
work on proportions
keep drawing the areas that are rough for you until you get better (could be eyes, facial expressions)
doodling randomly i found also helps me get better being in complete focus while drawing and listening to music helps if you don't already!
it also depends on if it's traditional or digital art! many different tips can branch off from there!
if you have any art idols on Inst a like any young artist would don't feel afraid to reach out to them and ask for advice on how to improve on certain areas you're struggling on!
and for drawing OC's grasp the character and input emotion into the drawing! it works best!
don't compare your work with others' works everyone is different and it's okay because it's special in their way
grasp what the meaning of the piece is supposed to mean!
most of it is accepting your art in your own eyes don't worry what anyone else has to say, if it's complimenting that's always nice! but if there is nothing nice to say just ignore it and continue
but for now work on the areas you struggling with just look on websites and find videos ~ get into the art daze!
hope this helps your artwork improve! if you have any further questions feel free to ask!
