A low-level biokinesis can be done by invoking some energy and then programming it. For example, for increased vitality, raise energy with the rune Thurisaz, and program it to give you more vitality. Spiritual planetary squares are more potent than the above, and can be used as well.
If you ask how to change your eye color, height, or some other similar endeavor, borne out of insecurities, forget about it. Focus on what is truly uplifting and helps you.
