Here's a sketch of the Rule 34 Queen herself, Tifa Lockhart.
She was actually the very first nude character I ever drew now that I think about. In middle school everyone was always talking about finding porn of her on the internet. So what did I do? Learned to draw her (the best I could at the time), made copies of the drawings, and then sold them.
Also, the tumblr (ya know, just in case something happens to the blog).
