Just found another Sonic avatar that some link was offline due the file was deleted, but someone had it and reuploaded, so I decided to upload it here
This model wasn't made by me! Published for use!
@Sonamy well, you need to download the skin. Then upload that skin on your own google drive (make sure it public for users, who can use/share this link). Copy the skin link you uploaded then paste it on virtual droid, while you're trying to add new skin
