Let’s just outline this:
1. You are free to use however many of them you like wherever you like!
2. You can even edit them and make your own for the trolls and other characters, anything you want! I provided a download to my .psd file for your unrestricted use.
3. If you make edited sets and want to release them you can. I’ll just add a link on my page along with the originals to your own edited set.
Scalemates, as well as links to installation instructions, can be found here!
