Alright man, you admit that you need tips
So I will gladly provide. One, get voice actors, its REALLY BORING to read text. You can search the voice acting club on google, and it'll pop up. Ask your request, you more than likely will get some pretty good actors. Two, most of your questions can be solved in a convienient section on newgrounds, called FLASH HELP (its a collection) just search tutorial and you'll get thousands of great results. Some obvious ones, lip synching, backgrounds, animation (the stick figures did look like they were walking, so kudos for that). And ultimately, if you look up a animation book in the library, or buy a wacom tablet (its a thing that lets you draw on a pad, and it is transferred to the computer directly) and lots of practice. Don't worry about full-scale projects, just learn how to draw, how the human body moves, and its correct proportions. In due time, wilth motivation and research, you can be a great animator. Look at Castle III, its a great animaiton right? Look at Castle I now. Similar to your submission. Look where the man is now. (More than two years practice, at least)
Hope this helps.
PS. The script also was weak, but dont worry about that now.
