Aaron Blaise is a former Disney animator, supervising animator and co-director of "Brother Bear", an animal-lover (see pic above), a painter and an all-around inspiring artist.
Blaise's YouTube channel is full of informative lessons. His site Creature Art Teacher offers a variety of courses. I just happened to catch a sale and spent the mere $49 for his Complete Animation Course (honestly, even if it were still priced at $129, I would've bought it. He's that good.)
I'm looking forward to downloading the 26 course files and starting the course about which I'll post.
Until then, check our Aaron Blaise's sites. You're likely to find something useful.
