Alright stiff and choppy a little this is. I agree with the below here and offer that the forums here on NG can be a source of wisdom for you. Don't get discouraged and ask questions, especially from more experienced animators. You're starting with sticks, I'd recommend going to Stick Page or Hyune's Dojo for more stick animators who may be able to offer great insight to you on your animations and how best to improve. POV Ray tracer might be of use to you. There are others out there that are free. I suggest asking around for which might be cool good or worthless as an unflushed piece of crap. Avoid those, Lol. Keep trying and hey you will get there.
