Alyssa is in the news for nonsense. I was trying to be funny.

I prefer your non-celeb illustration(s) as I'm not biased or over-familiar with the subject.

I take it you're copying from photos? It's certainly among the best ways to learn and refine your skills.

If you're interested, and if I may be so bold, I'd like to recommend the classic reference books of George Bridgman, many if not all available online free:

https://en.wikipedia.org/wiki/George_Bridgman

I had 3 of those books (gave them to my nephew), Constructive Anatomy, Hands, Faces, and just discovered there are 3 more!

I took life drawing for classical animation, so if you happen to find yourself seeking information about animation I can advise you on that. There is a LOT of material on it but really there are only a couple key books and the rest are a waste of time/money. (I prefer real books to digital.)

The first 3 may be mostly the same, under different publishing. The last one is the better 1981 version and is very technical. From both there are only about 4 key pages many animators keep photocopies of by their desk for reference.

Full circle piece of trivia, Alyssa Milano, before she got old and twisted, was the inspiration for Disney's Little Mermaid : https://scstylecaster.files.wordpress.com/2014/08/cartoon-inspo_ariel.jpg
