I actually made a video on my 3 favorite online art resources and why:
(I was guna post the link, but apparently thats spam, but it's called "Top 3 Online Art Study Resources (especially for learning Concept Art and Illustration)" if interested)
Here' the list (spoiler alert):
1) SVSlearn.com - Society of Visual Storytellers
2) New Masters Academy
3) Sycra's YouTube channel
I also have my own YouTube channel Fantastic Anatomy! where I've been posting all the tips and information I'm learning as I study for a career in concept at, visdev, and/or storyboarding. So far I have a character design study series where I look at characters like Pikachu, Wolverine, Powerpuff Girls, Cloud, Link, Piccolo, etc and see what makes them successful character designs and also anatomy tips videos.
Would love to hear any feedback on how I can make these vids more helpful, btw. The channel is called "Fantastic Anatomy!"
