I understand if you like these pictures, but DeviantArt wasn't made so you can submit something you like in your gallery, it's made so you can show what you can do and promote your own art.
You can't draw? Well there is something simple that you can do; take a pencil, take a piece of paper and go! Practice. That's the only way you'll learn how to draw.
But really, delete the pictures that aren't yours from your gallery. What you are doing is concidered as theft and can get you in troubles, especially now that the original artists who drew these are aware that you stole their art.
