It's good to see another trad artist here. I do edit my work digitally, but that's as far as it goes. As of now, I have never drawn anything in any program. 90%+ of what I do is paper, ink, brushes & pens...one of these days I may go back to graphite & charcoal. The conditions have to be right for it.

Hey, best of luck here! You're definitely right, in that more people use digital now. I have however found a few amazing traditional artists here, I thought you might be interested. Personally, I have a few traditional pieces here but honestly, I made that exclusively for about 10 years, and was ready to learn a new medium. I find the learning part very fun. Anyway, here's those creator links:

Those either exclusively do traditional art, or very recently tried a few digital works, but most are traditionally done.
