You can create your character, game, roleplay, etc. You could interact with others. You could even try to see other people's creations and see what they're like in order to get a feel for what your creations could be (without copying or breaking the rules on the wiki). Sorry if I being rude or demanding, but basically, as long as you follow the rules, you can do whatever you want on here.
I think you did a great job on it, though I think you need to add your character's personality section if you haven't added it yet. If you have, then sorry if I'm being rude, but still, great job on your OC.
