Recently I got the itch to draw more seriously than a rare doodle. I find their How to Draw course is perfect in content and style (https://www.wondrium.com/how-to-draw . I think you can get a 14 day trial for Wondrium to try it, which is what I did.

However, I keep renewing my sub because there are tons of great courses. Good luck! -KC
