Really cool design! And I love that texture! You really nailed down the look of a pictured sketch. It even has those rough, small smudges that really sells it as a traditional work!
If I may ask, what software and brush did you use? I just adore that kind of look in digital art.

Wow… Thank you! Yeah, I love the look of traditional work too, haha! I appreciate the observation a ton.

The program I used is Clip Studio Paint! I also drew with the Charcoal Brush and used the Soft Eraser for a similar effect you see on paper. The only difference is I was also working on an iPad, which has tilt functions in its pen.

I'm still trying to find the best way to approach drawings like this, but reading your comment really makes me feel better about what I've already done.

Thank you so much!
