I've had to delete the files you used from RedZaku, for the future; if you want to use files from DeviantArt: ASK FIRST. Once you get a reply, take it from there, generally artists get really upset when you just waltz in and take them.
It's not that I didn't choose not to give you credit, I thought the link to the original image page which I had put on the image's description was enough. I forgot to put your name as the original author of the image and what's worse is that I forgot to ask your permission first. I'm sorry. I didn't mean to anger you or anything.
