don't give up hurumi!

I think that you may need to copy sprites that you want to make. take those from blablue. copy them. trace them...
use the curve line and straight line
I think you can do nice things!

That way, you have a sense of anatomy and all the basics. Remember, your body isn't made out of weird, random, solid shapes. It's a three-dimensional masterpiece made out of cylinders and spheres. Make sure your light source is consistent (no pillow shading plz) and your anatomy theoretically correct.
Just some tips from a new pixel artist, what do i even know.
