I think it is terrible and unfair that someone as filthy as you gets to occupy my rightful place in the roleplay.
Just kidding. What you've got on the appearance is a good start. We're in the casual section, so I figure it would normally be deemed appropriate. I prefer advanced, but that's just because of the standard I hold myself to. If you want to expand more upon the appearance, take into consideration: body type, weight, figure, curvature, her poise, the scars and otherwise minor details that you might normally not notice, but in reality would influence you unconsciously how you would perceive a person. Let's say I were to make an unkempt 16 year old boy. Obviously he isn't old enough to grow a beard or some respectable lower face stubble, but I could describe the patchy, unorganized strands of hair coming from his chin, or the untrimmed fuzz on the far sides of his upper lip. I could probably describe sweat stains on the armpits of his shirt from working in the garage, or the cuts and calluses on his fingers. How he comes across a few inches shorter than he really is because of how he slouches. His eyes are red with irritation from his constant rubbing because his contacts are a size too big. There's a small chip in his buck tooth because his older brother throws tools at him.
It is very possible to write stories just be writing details about your character's appearance. You seem to have a bit of that in your sheet right now; I can see that she was probably part of a mid-to-upper class family from her hygiene and capability of affording braces - but obviously, it is not just mid-to-upper class people who can afford braces and keep themselves clean. As it is right now, I think it would meet the qualifications of a casual roleplay. This is just my advice to you if you really want to improve. :-)
