Thank you for reaching out to me, and I'm glad you like the assets. Feel free to upload them anywhere, modify them, etc. as long as you credit me (like you mention).
I hope you have a wonderful day :)

Thank you for your generosity and please forgive me for replying so late. A mod made with this asset pack has been released on Nexus, I post the link here!
You can click on this url to see the mod release page, where I wrote your name and asset URL, and some other content, and stated that "All benefits of this mod belong to penzilla."
Feel free to contact me if there are any problems and I'll fix it right away!
