Hi. The limbs look off because her arms are too long. To determine length: hands should be around base of the pevis area, the arm length doesn't change much when rotated around the shoulder. The lower half of her body also seems to be in different perspective than the upper (we can see top of her head and shoulders but legs suggest that we look from below). I adjusted the lines of the bottom part of the body to match perspective of the head/shoulders. I am no expert on traditional tools but you probably should work with one color, let it dry and then work with the next but also work on your values. Cheers!
