haha there are tons of sites that use the images. I simply can't be lurking around on the net everyday telling them to give me credits. thanks for being concerned . feel free to shout out to them on my behalf!
Google translate may help you. You should know that they should pay you to use your creations. But since they do not ask for anything, they must now pay you to repair the breach of copyright. Just my 2 cents of course
I would only suggest maybe using a darker (possibly black) backgorund instead of white, cause then the light saber effects can be seen a little better ^^ Other than that, great image, think it'll be my wallpaper for some time <3
