How to draw these characters?

[Iberian]

I learned how to draw TLK style by drawing with reference from the movies and from artwork.
This site has lots of screenshots and artwork from the production of the movie: http://pridelands.eu/folder1.html
Nala´s animator also gives free lessons on anatomy, drawing and painting if someone is interested: https://www.youtube.com/channel/UC0lLeNdvLrFozQRsQ1TQiAw

Yep, I've seen his work. Aaron Blaise.
There's specific ones for Nala especially since he did design her cub version.

Animating Nala: https://www.youtube.com/watch?v=afzOVPMCuEo (Includes a Q&A and him making different facial expression with Nala, was a cool watch.)

Nala rough pencil test from when the film was being made: https://www.youtube.com/watch?v=rnOEiNIhaTQ

then finally, just how to draw Nala: https://www.youtube.com/watch?v=w_npWFl5d7Q

And those are just within the last year alone, which is nice to see he's still actively working.
He uploads a few times a week iirc. He has some really cool stuff art wise. Crazy good.

While the screenshots aren't categorized like into specific scenes as they are on Pridelands.eu, Animation Screencaps now has much higher quality ones especially of the first Lion King film at 4K or 2160p resolution:

@Stormy, thanks for the video links, Aaron really knows how to capture life with his works.
@Timon the great, thanks for the animation screencaps links, what I really find neat about Pridelands.eu its the storyboards and concept art.
One of the artist who really inspired me when I was beggining in art was Andreas Deja, you can also see his works and understand how to draw Scar (really one of the hardest TLK characters to get right). Link: http://andreasdeja.blogspot.com/2011/09/more-scar.html

^ I think any LK film character is challenging to "get right". I've seen pro Lion King artists who mainly do lion characters like Scar, say that LK meerkats like Timon are hard for them to get right. Other artists say that the Disney type style is tricky for them also. So I can't really blame them.
