Points from the last face apply. Check out how ears look from images in google search and draw them as exactly as you can until you've got the hang of it enough to try a stylistic abstraction. Right now you've got a case of 'Boxer Ear Syndrome' if you ask me.
I know anime is an influence, but again, look at reality more. The way you space the eyes, the angle of them and the flat bridge nose in the middle is highly indicative of that you're trying to make do with mimesis and improvising whatever doesn't fit. You need more basic study of the human face, *even if you end up drawing cartoony stuff, waaay more cartoony stuff than this*. Can't really work around it. The individual facial features are well done, but when assembled like this their nature as symbols instead of features is made clear by the lack of geometrical cohesion. Start from the beginning, forget about poofy hair and what colors or scars the character has, start with the construction of the head and whenever you feel like you don't know what you're doing, study more. There's resources on the internet now.
Or you could keep at it on your own until a few years later you'll have solved a lot of problems in makeshift ways. That's fine too, most people strike a balance between concerned anatomy study and just following their muse for solutions to what looks bad. I just think what you're doing now is not the result of this balance. I say this because you seem to leave a lot of stuff semi-finished, which means you might think you don't have the patience or discipline for systematized study. If you're young, then you need to press yourself to get a system going because you'll never be young and have so much free time again, trust me
