His sketches have a lot more movement and grace to them. His sketches are absolutely beautiful.

The other ones you linked... I just can't shake the idea that Zee looks like she should fall over for being too top-heavy. :\ I know a lot of people like his work, but I don't, hahah. I appreciate that he's amazingly skilled at drawing and rendering and the technical bits of art, but I am just not a huge fan of his works, by and large.
