Done all of them. Not always easy to find the gesture. Some at level 2 as well. Tired of seals and sea lions :-)

I worked on the portrait reference. Still a lot of improvements to be done. Therefore, lot of practice seems a basic requirement! Pretty happy with mouth, nose and eyes while overall proportions are off

I don't have the tools to do an overlay but I think I've done okay. I got a bit frustrated towards the end so I ended up eyeballing more than I probably should have. My biggest frustration was how to block in the nose.

Definitely, not an easy one. Struggling to find the right spots and units... difficult to understand when things go wrong...

Struggling with proportions, but after the exercices are about lines quality... And that's definitely obvious to be confident and precise, with the right pressure....

Not happy of the result, but, have to deal with it :-(

Hand is not easy, the girll was finally easier than I thought... Any comment is welcome!

I drew both on a A5 format (kind of Statement format), too small. Therefore, lack of details especially for the captain.
