Topic: Art Academy missing lessons?

I had been eagerly waiting for Art Academy: Home Studio, and now it's here. I'm a little confused, though. Everything I'd read about it indicated that it would come with 30 lessons. The lessons screens show that there are 7 lessons for beginners, 4 advanced and 5 for tools. That adds up to 16, so where are the rest?

I am pleased with what I've seen so far. The pictures are of much higher resolution than I would expect from drawing on the Gamepad. I've enjoyed the one lesson I've tried. The lessons seem geared towards "artsy" projects: still life, landscapes. I'd love to see something more practical, like "here's how you can draw something better than stick figures", but maybe that's too basic. Still, it looks quite promising. If someone could set me straight about the "missing" lessons, I would be even more pleased.

Still life and landscapes are more basic than drawing people. To draw people you will need to use the techniques you learn from those lessons
