I have long heard of internationally acclaimed artist Emily Ball, but finally have taken a deep dive into studying her work. I recommend it! (Pun intended: Check out this great video on her swimming series here.)
She also teaches at Seawhite Studio in England, but some classes are offered pre-recorded so we could take them too.
In addition, she has a book out: Drawing and Painting People: A Fresh Approach , which I will probably delve into next year.
