The idividual known as gfoyle took my artwork (the Doctor Who Logo Wallpaper) and merged it with the work of another artist and submitted as a deviation under his own name (here)
Although I appreciated that the artist acknowledged that he used my artwork, I did not apprecicate the fact that he did not ask to do so or notify me afterwards. I only found out when someone favourited both my artwork and his "mashup".
I've sent gfoyle a message asking him to take down the artwork. I am waiting for a reply.
