Why do you feel the need to source art that is already sourced by the OP? You're not helping anyone you're just being obnoxious and self-promoting.

We know it’s incredibly important to source artists when posting their artwork, which is why we always link back to their deviantART accounts both through the caption and the picture itself. However, we don’t always have a way to find deviants’ Tumblr accounts, and even then not all deviants have Tumblrs. Therefore, we cannot always reblog the original post or else we would do so. Including a link back to the artist’s profile ensures the artist gets credit for their work.
