There are a few advantages to shooting in RAW but it's a comparatively small consideration next to all the other things that make an interesting photo.
The most important (technical) things to think about are maybe things like the differences that you get from different focal lengths - ie if you stand near something and take a photo of it with a wide angle lens it looks very different to of you stand far away and use a telephoto lens, even if the thing fills the frame in much the same way... and the difference that
depth of field makes: you can correctly expose things various ways but the
way you let a quanitity of light through the lens affects exactly hom much will be in focus...
So those are the sorts of things I'd play about with before worrying
too much about whether you're shooting JPEG or RAW files...
Have fun and post lots of pics here
