Please link to the specific textures used.

EDIT: Fixed, thanks! :)

Thanks.

• ✅Unsplash textures are only compatible with CC0 if they have been heavily modified, which these have been. All good there.
• ✅I don't see the gloved hand texture used in this model, but maybe it was just modified so much it isn't recognizable. That's fine, but where did Jhonny's clothing texture come from? I don't see that listed in the textures. EDIT: custom texture created by OP
• ✅The Hippopx texture is CC0. All good there. 
• ✅The texturelabs.org texture is NOT compatible with CC0. This texture will have to be removed or replaced. From their terms page: 
• "...Specifically, the resources cannot be ... included as textures for a stock 3D model."
• Texturelabs resources cannot:
• Be sub-licensed, resold, shared, transferred, or otherwise redistributed (even for free).
• Be distributed or sold as part of a 3D model in a way that allows a third party to use, download, extract or access the Texturelabs asset.
• ✅Per OGA submission guidelines, 3D assets must have all textures credited (even if the textures themselves do not require attribution) either in the submission description, or in a credits file inside the downloadable file, but preferably both. Please indicate the texture sources in the submission itself, not just in the comments.

Thanks again for the quick reply! Nice work on the model. :)

Nice! Good job on that custom texture. It looks good. Let me know when the shoe texture is replaced. :)
