mate, what can i say? fantastic, love the model, adore the scene. lighting is ace, can't believe you did it with so few polys.
but i think for a bit of a laugh, you should do one last render, simulate the pose of "Uma Thurman" in KB2, with the two fingers and blade parallel to the floor & next to her head! that would be a great pose!
Well done dude and Good Luck!
