there will be some posts telling you to take a look at some tutorials (which is not a bad idea) but i'd say you should try out some stuff by yourself... but as i said, tutorials are a good idea.
and here is an important note: PLEASE, please: never spam newgrounds with crappy stuff just because you're too lazy to practise! there are enough stupid little kids on NG which do that kind of spam. you can become very good if you practise and since you got the newest flash version you should not waste it!
