Would like honest feedback

Hey guys I just recently started drawing and I wanted some feedback about these specific drawing


Drawing #1

This one took me awhile I was looking at a picture it was cropped but I tried my best




Drawing #2

I drew it from a book by looking at it and I noticed some errors I made but overall I think I did decent




Drawing #3

I was a little bored and I wanted to draw this I wasn't sure what I wanted to add like blood dripping or anything else etc

The style choice on the 2nd drawing is very unique. I feel like in the 3rd drawing, your lines could be a little more curve(y). Lastly the first drawing, the shading. That's all. But other than that, their awesome

Someone who doesn't come from an artistic background what-so-ever.. It looks okay. Better then most, but def not professional.

1st one, missing a couple of lines in my opinion (Around the nose area) but is nice, 2nd one simplistic but still nice and 3rd one I like the most, with lil corrections here and there

these drawings are nice. but needs some work done in shading.
The technique of shading is called hatching. YouTube some of it's tutorials
There are different types of hatching which are used to get a variety of results.

Pro tip: download/buy the book called 'Drawn to life - The Walt Stanchfield'
it's a book by Disney and covers everything you need to know to become a pro artist or animator
