Tutorial - Curves on Girls by *Ai-Bee on deviantART. Reaaaal good tut on different body types. In her deviant there is also a lot of links to others tutorials for men and women body types. If you draw characters, go see this.
I like the fact that the main content on the page never disappears, although the interacting with the side bar is at an all time high. It& a very clean layout with flat ui colors that speaks nicely to the flow of the app.
