Thank you everyone so much! I've been stupidly busy recently with the MA I am doing in Classics so I haven't had any time for illustration.
I looked up tricksy dolls and they do totally look like that.

It's nice because it doesn't patronise and pretend that their aren't rules to drawing from observation but also makes you feel like you can let yourself off the hook for getting things wrong.
