There are many programs currently available on line.
These are 2 that I have taken and can recommend.
Kevin's on line program is affordable and is serious stuff without the fluff.
Challenges inspire to create projects that directly effect your current work.
An organized and concise program in a safe professional and respectful format!
If your desire is a meditative and thought provoking program, and are seeking a conceptual approach to your work, then I recommend Bernd Haussman
I support all artists who are seeking to inspire and will continue to pay it forward.
If any artist is in need please contact me personally to apply for a scholarship to online programming.
In addition, I also offer my services for 1 free crit to any artist who is looking for a professional objective opinion. Email to email@example.com I will reply in a few days with a mock up and comments.
Be sure that you are comfortable with critique, and remember YOU are the artist.
