Hair - dark brown / black. hair should be styled nice and trendy, girls make the effort so men should too lol
Height/Size - atleast 6', toned, not bothered about muscles necessarily but a hot body is a bonus
Eye colour doesnt really bother me, dark eyes are nice but really light blue / green is striking
Style is important too, trendy but not pretentious / too OTT
Apart from these, a great smile and good skin get my attention.
Of course personality is more important ... lol
