Hiya, a noob animation? Thats awesome, the head even bobs n everything. Great attention to detail. Im also a newb so i cant offer much advice. I have found tutorials on this forum are incredibly handy and people are always happy to help, give advice and even offer up code. The thing that confused me, is AS seems to be a lot like russian dolls. I.E, there you'll have an action, within a button, within a movie, within a movie, within a layer, within a frame, keeping track of all that, is pretty confusing. Buttons, for what i know of them seem easy enough. Create a new symbol, as a button, then open the actions of that button and tell it what you want it to do. Anyway, I'm no good at giving advice, I just started myself. Try looking here if you havent already...
