They're all digital! I used a wacom bamboo tablet, though I have since used an XPPEN Star 03 and currently use the XPPEN Deco 01, which I love the most so far. They're really fair priced tablets and well made.

I used Medibang for these, which is a free to use program for pc as well as tablets/phones that I use for all of my art. Hopefully to post more soon!
