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
