The learning curve is tough, but I think without the book it would be almost impossible. If you are thinking of starting modeling with Blender, I would suggest the 2.3 Guide. I said I wasn't going to post a picture of the Gingerbread Man, but I worked hard on it.
Tomorrow I will add bones and animation. I really can't wait until the light comes on and I figure out how these models get into a game (and move the way you expect them to).
