Here is my Sketchbook to practice on something more than just Digital works.
I have been working on digital art for so long I kept trying to pinch my canvas at times, it was weird.
Also no UNDO button is scary and my hand isn't too steady with no digital stabilizer.

These two pages are done with a Sharpie Marker and a Sharpie Pen, I was curious to see how bad it was to work with.
