Welcome to the wonderful world of photography.
I asked myself this very question almost four years ago. I have this gear, now what?
Everything that has been said, is all great advice. The internet is a vast source of free material for you to learn your camera, and perfect your skills. Starting right here on the photography forum, to the millions of youtube videos. (Though, not all of them give sound advice).
But no matter how much you read, or how many videos you watch, nothing changes if you don't get out there and shoot. I recomend getting used to shooting in RAW format. Don't be afraid to get out there, and try new, different things. Even if a certain style, or theme doesn't intrest you, attempt it, challenge yourself, do various personal projects. By getting out there, and shooting on a daily/weekly basis, and trying differnt things, you will begin to learn more about yourself, your camera, and the things around you. What looks good, what doesn't, what intrests you, what doesn't. You truly won't know, untill you try.
Good luck, and I hope you enjoy it!
