It's a great little book, nice for a beginner, but somebody will a little more experience would probably enjoy it too. There aren't too many traditional models in it; variations on traditional models like the sailboat and the helmet or kabuto are marked as such. The projects start simple, but increase in difficulty as you progress through the book. I didn't try the chess pieces or the owl yet, I'm saving those for another day, but out of the rest of them, I'd say that the angelfish is probably the most difficult. His version of the swan was interesting. It was quite complex. I'm not quite decided if it's easier or harder than the traditional model. I guess I'd have to do a few more for comparison, but the end result is just as pretty. Highly recommended.
