I've noticed that water moons give depth and enigma whilst air moons are usualy popular and well-liked.Earth moons give good bone structure(esp Virgo and Cap) whilst Fire moons can either be very outspoken(and therefore not liked) or really vivacious(thus popular).
I know that these(notwithstanding the earth description) are all personality traits, but I think they affect beauty and how one comes across to others.
In my experience, the moon sign is telling on looks.
Air moons tend to be conventionaly good looking(with the exception of Aquarius who can be really awkward looking or unbelievably stunning in an "out of this world" kinda way). Libra moons esp tend to be quite pretty(even the men).
Water moons are usualy reserved but warm. Many have beautiful, warm eyes espec Pisces/Cancer. Scorpio eyes are freakishly expressive and even probing ; in an unrelenting sort of way(if ya into that sorta thing).
Fire moons are also good looking or pretty. But many tend to lose their looks when older or not take care of themselves much; especially the men.
Earth moons bloom into beauty. Capricorn/Virgo especially can be plain for a long time and then bam! all of a sudden, they become really stunning.
Taurus moons have "flat" eyes. What I mean by that is that the face may be rich in features; thick lips, luscious brows, dimples, ski nose etc. But the eyes seem unexpressive or dull.
Venus also affects the appearance as there are many Venus in Scorpios that are ridiculously hot. Venus in air esp Libra gives proportion(true) and very good manners. Venus in earth, esp Virgo can make someone really attractive but oblivious to their looks. Many "discovered" models have this placement
