I understand you're concerned about art theft, and that someone's own effort and talent can easily and unfairly be made as an available resource for people to use widely. To answer your question, yes, they were taken from the dA site. My assumption that this is a well recognized and commercial trademark, and I made these resources with the intention of promoting DeviantArt and it's endeavors.
Do you feel that I need to take this entry down? Or if you feel this is a better solution, do you think you can provide me a link to this artist to give where credit is due.
