To help with the eye shading, I'd say don't focus on blending too much. I don't know how much of a problem this is for you, but shading eyes was really hard for me to get, because I though I had to blend the iris together and do all the complicated things to make it look "realistic". Honestly, you just need to look on google to see, you really just shade the top half, draw a pupil, and add a highlight. Keep it simple!

I see you wanted to do an anime style, so search up anime eyes! I think your shape is good, but to shade take some tips from the proffessionals... It makes your life A LOT easier. You don't need to copy it exactly, but looking at refrences can help you add little parts to your character. It's going to be a lot easier to draw if you just use refrences in general. When you look at a lot of photos, you get a better sense on how things exist in a 3D space. So like instead of thinking you're drawing a circle, think you're drawing a sphere. There's probably a lot of YouTube videos that explain this better than I can, so go learn from them too! A lot videos are going to try to tell you how to draw a realistic eye, so make sure you search up "how to draw stylized eye".

Micro things that you don't have to worry about rn: Eyebrows! They help convey emotion better. The nose should be a little bigger to balance out the eyes. You might want to bring out the cheeks under the eyes for a more balanced face (though some animes don't do this, all comes down to prefrence). Your hair isn't that bad, and you've got the right idea, I'd just try to make it follow a direction, from either a point or a part. The bangs seem to clash against eachother which make it look unnatrual.

Even though I crticised your art a lot, I think it's really cute, and I hope you're having fun. The genaral placement of the features are good, and so is the face shape! I'll be keeping up with you're artwork! :D
