Johxatann Designs (Copyrighting)

I have some fans asking me to give credit to authors for there work. Everything I use from their designs I do give credit. But most of the time, I find them from using google.com or yahoo.com, and they don't give credit to the original owner. So i wanted to give credit to the owners and say sorry if i don't personally use their name because i cant find where they gave credit. My designs i redesigned and im not going to use them for commercial use. these are personal designs i use for my Angel KairiRay007, or I use them to express myself, or a design, just to design it. So sorry if i dont personally give credit to you, but i will always try to copyright if i can find it. But i hope you guys like my designs and i have more coming soon
