To be honest, I don't have the original pics. My last drawing I posted was also based on a graffiti artist's work. I'll try to find the pic again. I can't delete these posts, which is unfortunate. Anyway, you are welcome to dig more if you feel so inclined. You'll probably find more of these posts.
All the best.
Dont worry about not having the pictures, just go ahead, come clean and tell us and the community which ones of your works are based on other artist's works.
I will try my best to dedicate a post to that, but it might take a while. Thank you for your understanding regarding all of this.
