The construction I used was a sort of rough lazy Reilly method. I thought I could get away with eyeing more of it. Apparently not.
I actually have some tabs open about how to do caricatures -- really neat set of tutorials by MAD Magazine artist: How to Draw Caricatures by Tom Richmond
I'll try to set some time aside to learn planes and Asaro head stuff properly.
Thanks for the help! It's been really useful as always.
