I agree with the height and the hair. It's a good basis for our appearance. As for weight, I would suggest slender and lean, rather than an equal amount of fat and skinniness; maybe with corded, thin muscle that wouldn't strike down the ethereal, God-like form, but enhance it...barely noticeable, but noticeable enough for stubborn humans to not pass us off as weak, and for weaker humans to not pass us off as a muscle-bounded brute. As for eyes...perhaps golden. A deep golden would suggest power, but it wouldn't immediately strike us off as good, nor evil. Golden can be rather neutral...although it may accentuate the 'light' aspect. I don't know for eyes.

How would an amorphous face work? Would it change depending on the viewer, or something?

I'm neutral to clothing.
