Beginning photographer?

[Erin]

So i'm a 15 year old extremely interested in Photography.
To narrow it down a bit, Nature photography.
I will go deep down in the woods or crawl through the grass just to get the perfect picture.
I have taken quite a lot of photos already, and have posted them to Facebook. So people can see it.
Many of my friends, and family have taken some of my photos and used them as their wallpaper or screen saver, and have told me how many compliments they got, and told them i took it.
So i was just wondering how are some ways i can promote my interest in photography, and kind of get the m out there? I already know i could like join photography contest and such.
Is there any important facts i would need to know about taking photography?
I have a photography camera, and mad editing skills. Not to toot my own horn or anything.

I would just like to find some way to get my pictures out to everyone outside of my friends and family.

Any Ideas?
