While I am responsible for creating Drakow's profile theme / signature / avatar etc.. I did not actually create the image of Hydreigon itself. Assuming that's what you're talking about lol. The wallpaper came from a collection I have downloaded. (There are a few of my favorites in my "Profile Themes & Signature" Album if you ever want to see them.)
I would be more than happy to share if you ever want to use one for yourself!
