There are plenty of places to find good bases, like groups, or pixel sites. I know dA's pretty much crap for finding good bases, but you gotta look at it from the other doller's point of view. If they spent that long looking for the base, then you just say, "hey, can I get the link to that?" it's kinda like... well, it's frustrating. But like I said, you can find the base in her gallery. She separates her art into folders, so it should be easy to find, unless it's an exclusive base, in which case you'd have to find it on Glam.
I understand. Im sorry for being so rude...Your picture really is amazing. My stuffs really crappy compared to yours. hah I mean your shading looks like it took tons of time. The hair looks so soft and detailed, which im sure it is.
