Well ahem. Actually, I understand but dA is an art site, not Tumblr or Facebook... so it's where people show their own creations. If you want to share these pics, feel free to do it on social sites, but not on DeviantArt. I'm sorry but I'm afraid you have to remove all that isn't yours. Plus you don't seem to have permission of the authors.
Try to draw for yourself instead! :3 There's always a beginning.
