Can't work off much without the app, chief.

That said I probably wouldn't worry too much about originality, personally. But I don't know the GM or the group or anything. Instead I'd be focused more on how the character reacts to circumstances and how this built them as an individual going in, what flaws they have and would propel them through the plot; consider how these can be resolved and in what way and how these create new conditions to move the character in another way.

But really lacking details on anything over all to say in confidence what you should look at and consider. But if this is reflective of anything, it's that you didn't do a detailed enough character and presented a barely formed mass.
