You really are so very pretty.
From my heart, though....I wish you'd just ....smile ...a little. Even if you don't smile a huge smile, but just think about something that makes you smile before taking a picture of yourself. It's amazing how just /thinking/ about something that makes you smile can change your whole visage in a positive direction.
In other words, as beautiful as your outside is, your insides would shine through your outer beauty and you'd be /magnificent/ if you just relax and let yourself feel a little happy! Your discomfort with taking pictures of yourself shows on your face.
