SVS: Society of Visual Storytelling
This Last semester I got to take a course from Illustrator Will Terry at UVU. We covered the principles of design, the business side of Illustration, how to improve personally and other topics. He helped each student become better no matter their level of skill. He also showed us parts of his lessons at svslearn.com
of which he and Jake Parker are business partners (I now have one of these SVS lessons and it's great). It is dependent on you putting in the work but that should go without saying. If you are serious about learning I wholeheartedly recommend these courses for your consideration if they cover topics you are interested in.
Each lesson has video tutorials some have royalty free materials, critiques and for certain lessons live streaming help with your work. Will Terry teaches some of the courses and Jake Parker Teaches others and some are split between them. There is also a Painting Fur lesson taught by Therese Larsson
and a Z Brush Sketching lesson with Jose Cua
Just wanted to share this for the benefit of the artists involved and the community.
I hope you have a Great One
