i'm going to say Libra. He's very well porportioned physically. He also has great posture which Libra's are known for. There's also a refined presence; a peaceful easygoing charm about him..
Spica you got it he's a Gemini. Sagittarius is a good answer (opposite sign), Libra/Taurus and Cancer would have been good answers too. I guessed Libra.
I have that friendly smile too it doesn't get captured well in pictures though, the friendly warm generous toothy smile which is evident person to person interaction.
I'm a Gemini Lady M you should have known that buy now. Phlegmatic qualites? associated with Water signs? This one author mentions this, Fire - choleric, Air - sanguine, Water mentioned and Earth melancholic. What do you suppose the phlegmatic qualities are Lady M? I once did a dictionary search on the word and didn't see the association with astrology.
TaurusBabe that color is a mixture of blonde and brown, I applied both first blonde washed off then applied dark brown.
