I used donor embryos and there were only three caucasian profiles at the clinic at the time - my second choice turned out to be a hispanic profile. One of them, the personalities and accomplishments of the donors really spoke to me but there were no picture at all. I knew the egg donor was short and a bit overweight with dark hair, somewhat olive skin, and brown eyes. I am taller with blondish hair, fair skin, and blue eyes (donating family father also was fair and blond but average height.) My kids totally look like they could be my genetic kids. Both are blonde (son has curls like me and daughter, waves) with face shapes, chins, and mouths very much like mine.
Not that you should decide one is "good enough" but if one really speaks to you, I wouldn't worry too much about appearance. (I know some here will differ but that is my perspective).
