I'm not that good at giving advice so pardon bad english

I would suggest trying to copy a few peoples styles that you like, then try drawing your own.

Try to do Realism, and maybe some anatomy practise.

Thats all really, I'm not that good :'O

Oh look, a perfect opportunity to try to remember what I heard in that one video I watched 2 days ago. :'D

The best way to improve is to look at references, sketch them out step by step (so don't redraw it just how you see it, but try to understand the proportions and how to sketch it out using basic shapes). Later on, you should draw the same thing but out of your head and try to recall what you learned/remember. This will help the information to be stored better so ya don't forget it that easily.

About the style, try a bit of everything. Try cartoony art, try realistic, try chibi, every style you like, you should give a try. Then later you will find one that you prefer over the others. Don't be afraid to take small things from other styles and put it in your art, because after all, you will keep improving to the point where for example the nose you took is completely different and your own. Just don't take whole styles from someone, try small things and combine them into a new style.
