I want to enter the photography competition, any help?

I really want to enter it…
So I have the http://www.photographyblog.com/images/sized/images/uploads/olympus_fe_4000-550x374.jpg. I got this camera as a Christmas gift. I haven’t been using it a lot so I really don’t know how to change everything and stuff.
Can you guys help and tell me maybe how to take good pictures and all that.
