The left eye is out of alignment.
Of all the ways to draw out there, I think anime is one of the most structured.
I would approach a drawing of anime like anime is drawn.
You are painting this like a life drawing. And that's a good thing. But my recommendation is to use this tonal technique to do humans and make the other more linear.
First thing to do is get a model -- find a pic of this character and draw from it rather than out of your head.
But if you want to simply develop this, get the model still, but on a layer work on the structure. Make a layer and find your construction lines and place the parts where they belong.
That's if you want to do this character and/or draw formally.
It's a cool early drawing. It's fun when something just magically appears when you have a marking tool in hand.
Keep going!
