Beauty isn't a certain hair color or eye color or anything like that. There are plenty of beautiful women with blue eyes and brown eyes and green eyes, etc. etc..
You mentioned "tall" - I find tall women attractive. A woman my height (5'10") or taller gets bonus attractive points for being taller.
I think beauty has a lot to do with cheek bones:
...and attractively shaped eyes.
Also a girl can be cute and be as attractive as a gal who's beautiful. Here's a girl who I don't think is beautiful at all, but she is really cute (there's a difference between "beautiful" and "cute"), and since she's so cute, she's really attractive - and I'd probably date her over anyone who is beautiful.
