As stated in the original post:
You're welcome to use any of the models in this pack on any commercial or non-commercial project, and there's no need for you to ask for any kind of permission. Yet, you have no permission to re-sell the models as a part of any asset pack or on their own.
Credits are always welcome, of course, feel free to also show me pics or links of anything you made using them!
That being said, it's all under creative commons 4.0 (you're free to use my sets, just don't re-release sets including my work, you can still use it to create stuff freely, anything from comments and ratings to suggestions and donations is always welcome).
