Hello, can this art be used in a commercial project?
Yes. I just ask to be credited. And if you need a freelancer think of me <3
So is it CC-BY4?
If yes, you should add the license into metadata for the asset packs:
"Edit asset pack->Metadata->Release Info->License for assets" It will increase the size of audience that will be able to find your art
Thank you, sorry for the delay on changing things. Had some rough months.
