Redistribute my work with credit for non-profit purposes, after asking me first by sending an email to firstname.lastname@example.org. In most instances, I will allow it.
Use my tutorials for reference and art development, with credit. No permission required.
Profit from fanart of my work, so long as you make it clear that my characters / concepts are featured. No permission required.
Create parodies of my work, as long as you credit me as the owner of the characters / concepts featured.
You may not:
Trace over my artwork or make clones.
Copy my ideas / concepts / images.
Profit from redistribution of my work, without my written permission.
I enjoy seeing fanart / parodies of my work, so please feel free to show me what you produce by sending an email to email@example.com.
