Agree with all. I too got the same camera, my first DSLR, a few months ago and I just took it outside in the backyard and started shooting. I put it in different modes and shot the same scenes for comparison. Figure out why the shots look different in different modes, what you like, what you don't like, what went wrong and how to change it. Read up about your camera so you know how to use it and use all the resources here on DPS for photography in general.
I also can't wait to take my camera out into some open country! Good luck!
