Ususally when one comes across an arresting image on Tumblr, there is no easy way to determine its provenance. It's a matter of accreditation. Happily, the person who posted this lovely image included the artist's name in the file name. Therefore, I can point you to the Deviant Art page of photographer RockerTannz.
