Hi o/
I'm building a foss engine under GPL3 and this asset you created is very interesting, it would made clear on my examples that it is a template for a character.
But your license terms make it ambiguous if I can use it in this context since I would have to pack your image files with the code to make it usable.
As you understand it, Is this considered "redistribution"?
Maybe you could consider using one of the Creative Commons licenses to avoid this ambiguity in the terms of use?
