I know the feeling. Unless inspired, writing can almost be physically painful for me.
1) Read through the approved characters to see what is expected.
2) Start simple. Don't try something overly complex to begin with. You can make a really great character without all the subrace stuff.
3) Make a character you can play, and want to play. Layo is about playing a role, so make it one you can have fun with.
The character approval GMs are a great bunch, so go ahead and give it try. If it's not perfect they'll make suggestions on what they need to get it approved.
