Excuse me, but I am unsure about the limitations imposed by the license:

- Is it ok to use your work in a freely accessible, time limited, interactive online event? (https://workadventu.re/, https://github.com/thecodingmachine/workadventure)
- Is it ok to scale and change your work? (Image scaling, recoloring, tracing, over painting and so on)

Everything of cause with references in some sort of credits!

Best regards

Hi Harfi. 

You can use the ressources in anything you want, when you bought them.

Of course, you can use, mix or transform the ressouces as much as you want :) It's artist friendly.
