My one hint for you is description. If you can describe something in one sentence, the chances are you can extend that into two. From two, to four, and from four to a paragraph, and so on and so forth. Try it with the color red, or the clothes you're currently wearing. Once you've got that down, everything else is just finding out what suits you as a writer, what suits your character and what's fun. Thesauruses will become your friend, trust me. You've already done the most difficult part, which is creating a character name.
If you ever get stuck, don't hesitate to ask a million and one questions about everything!
Hopefully we'll be seeing you in the fray soon enough.
