I'm actually a day late (on my schedule, anyway) for this, but in celebration of 's birthday I made her a picture of Tsunade-sama, whom she resembles to a frightening degree. Against her, what wall, what boulder could stand?
This is really, really, really well colored. I'm especially eyeing her arms and face, but the whole thing is shaded awesomely. You've come a hell of a long way with coloring techniques. As always, I love the lineart too~ The hands are nicely positioned.
