I'm not the best with computers and could never get into digital art. I know I should probably try to learn a little about it, but I just prefer the traditional method. Art Academy on Wii U does look pretty cool for learning digital art, though.
I too have been wanting to start over and improve my work, and thinking about finding another site to post my art, or better yet, make my own personal site. People always ask if I have my own site, so it's certainly something I should look into.
