Alright: so, the tutorial is pretty decent. Here are some things you could do for an improvement:
1. Teach how to make a run/walk cycle. One of the things I did with sticknodes when I was extremely unexperienced with it was always making the stick figures jump to move because I didn't know how to make a walk or run cycle. This thing is very important. I mean, yes, you could use the "charging" part and all, but I think going a little further into the subject of walking/running could help the watcher.
2. Teach basic animation principles. You don't need to go to far in the subject, just tell them the basics and that if they want to know more about them, tell them to "look in the internet or in books."
3. Add anticipation in your punches. That one is very important. Especially because in the next slide, you're pointing out the anticipation frames, and yet you didn't in the last one.
4. Add a way to go back one slide. Just do that, that might help a bit. A small knitpick, but hey.
But still, I think this tutorial could help a lot of beginner animators.
