A study on Juan Guarnido. Different medium but I tried to replicate what he's doing.

All three Level 1 drawings. I tried my best to keep it clean, but I feel like I’m still having problems with drawing smooth lines. Appreciate any feedback and criticism. Thank you in advance.

This is my assignment, before watching the Demo. I did use the eraser as I didn't realize we were not supposed to :(

Proportions are somewhat off in the skull but I like it. The camel is pretty bad, I will retry in the future.

Boots were very difficult but I'm quite satisfied with the result !

I think I oversimplified the shading. Also I think my pencils are not very good :(
