just a little constructive criticism on #1 here...in all kindness, of course.

about the hair... one side is swept around the neck, and should be a bit shorter than the rest. also it seems a bit stiff, I usually draw hair slightly wavy to make it feel more soft. and one more thing... since the globe seems to be a focal point, you may want to outline the arm so it's a little sharper than the other to sort of lead the eye from the face to the globe. Keep up the great work!!
