My art teacher required us students to submit 3 of our favorite sketches from our personal sketchbooks that we were comfortable showing the class. We need to show a understanding of anatomy and creativity with each piece. Does my work reflect that? In other words are these drawings good?

Yes

Explanation:

I'm saying yes your drawings look good! I love how you used shading for the character's clothes, hair, etc. And I like how you drew the body base well!

See below.

Explanation:

I think you're off to an amazing start. I noticed you're hiding hands with long sleeves, I'm not sure if that was intentional or not. I think every artist goes through that. But, the best way to improve it to draw a full body, including all the parts you really don't want to draw, look upon it, and if you look at it in disgust, you've already improved. I really do like the first one, that is my favorite hands down. You're already wonderful with hair and expressions. I love how you experiment with different styles.

But anyway, every artist has a different way of drawing things, some do shading whilst others do not. If you do wish to do shading on drawings, the best bit of advice I can give is use references. Whether it be in real life, or based off other anime styles, references are always useful to learn techniques. Being self-taught has its perks, but as one who tried to learn by myself, without references, it sucks. So use references.

I cannot think of any other pointers at this time, but anything in particular, I can probably help.
