Complety royalty free, 100% Common Use both privately and commercially. I give this statement as the original artist of these models.
Having been made in Blender 2.79b, there are two files aviable. FBX and .blend. I went ahead and modified the ears and added some textures, eyes and eye lashes.
**Update**
l am currently working on a volunteer developer based project recently started March1, 2021. You can contact me on FaceBook under the company name Sybirathia LLC and its web address is https://www.sybirathia.com/ if anyone else is interested in lending their creative talents to the project. Thanks again everyone for your interests in these models. :)
