As far as proporions go, with the height you're spot on, about 6.5 heads tall. Her arms fall down to mid-thigh, good. Her feet are a little small, they're supposed to be about the size of the forearm. Her legs are about the right length compared to the rest of her body. No real complains there, I don't think you need to worry about awkward proportions.

As you're going to be touching up the lines with a pen, I don't think it'll be such a problem that some lines need a bit of erasing. I think that'll all turn out pretty well. I'll be waiting for a finished product!
