A friend of mine at the clinic always says a man can learn a lot about a woman by just looking at her hands so you are not wrong there. He told me that he always checked their hands. No matter how attractive they are if their nails are longer than they should be, he moves on.
For me, I tend to look at the eyes and the smile first. Height is pretty important to me as well in the sense that I want to be able to wear heels without being taller but I am only 5'4 and wear 3.5 inches heels max so 5'8 and taller for me is fine. I like to watch how he carries himself as well. I look for confidence but not cockiness. I also have to do a smell check. I have a very sensitive nose and if I don't like the way you smell, we are not going to work out! lol
