I am very glad you found them useful and enjoyed them! I made them myself four years ago as a student because I was in the same situation :) For future reference and projects, times have changed, and there are now some sites that offer much better work under the same licences. You may want to check out sites like https://texturehaven.com/textures/?c=wood&s=bark&o=popular or https://cc0textures.com/which generally have amazing quality all under CC0 licence.
