i am doing good ~? any advice what can i do better ?
This is really good spooky! I’m a big fan of pencil drawings.
To get better you should understand the human body. What about https://www.innerbody.com/htm/body.html ?
You could study anatomy. If you just draw like that without any higher knowledge, then I guess you will not make big progress. I have not a lot of idea of art. But at YouTube they say you need to understand the basics. I think you must learn to get better and not just draw, even if you just draw, as a great artist you should understand how the things or people, animals are build, inside and outside. And of course draw a lot.
